Getting loud is an art form.  Some come by it naturally, others have to work at it.  The most important thing is giving it full effort and then sustaining that effort until the game is put away by your team.  Proper technique is key to getting loud.  Let's start by addressing the week of the game.  The bottom line here is saving your vocal cords for kick off.  As a result, try not to smoke or drink alcohol to excess.  This damages the cords ever so slightly and reduces scream resonance and overall volume.  This may call for skipping other sporting events or wearing a muzzle if you must attend them.  Do not yell at your kids or wife in the days before the game. A side benefit is that you will seem like a good guy and get more of a pass for the weekend from the family.  In reality, you are just saving your voice for when it matters.  Do not yell for your kids to come in for dinner or call for the dog.  Game week is a good time to substitute with a whistle or dinner bell.

The day of the game, begin to drink to excess.  Although there will be slight, residual cord injury, this is overcome by the fact that you are getting into the right frame of mind for reaching maximum scream potential.  I never saw a sober guy scream with any real pop.  Conversely, a drunk is like Bill Bixby just as he turns into the Incredible Hulk.  Overindulgence in alcohol aids in anger maximization and allows the cords to loosen up sufficiently.  This also helps to overcome natural shyness or inability to get worked up over a bunch of kids playing a game.  Forget the smokes, though.  Radiation will get you over any cancer issues but losing your gameday timbre simply isn't worth the risk.

When the game starts, remember a few basic "don'ts".  Don't scream when the Gators have the ball.  In fact, don't even say a word.  Just practice your breathing and, if we make a big play, nod knowingly and slap some high fives.  Just save the voice.  Don't yell for the coke guy.  By the second week of the season, you should have already perfected the "Yo, I need a Coke gesture".  If you have been diligent in your preparation, you should be able to get the vendor's attention from at least 4 rows and 17 seats away without ever opening your mouth.  Lastly, don't gulp your carbonated beverages - it will simply build up burp gas which could devastate an otherwise perfect scream.  

When the opponent's offense gets on the field, immediately stand up.  As their offense breaks the huddle, begin to lean into the direction of their quarterback.  Lean as far as you can without falling into the guy in front of you.   Most of the game you will need to lean front and to the side at the same time to get your mouth as close to their offense as possible.  Don't worry about the fact that you are actually 70 rows up and 80 vertical yards away from the other team.  Every inch counts, so lean hard.  Wear ski boots if you are concerned about balance.   At the same time as you begin to execute your lean, cup both hands around your mouth.  At this point, begin to scream.  It is critical that you hold the scream from the time they break the huddle until just after the ball is snapped. I find that a lower cambre OHHHH sound promotes maximum volume while reducing the scratch factor.   If you are doing your job - standing up, leaning toward the opposing QB, cupping your hands around your mouth and screaming as loud as you can from the moment they break the huddle until just after the ball is snapped, you have no real way of knowing how loud it really is.  You can tell its loud but you can't really hear it well because you are screaming yourself and you can only hold a scream for so long without passing out.  If you being to feel peaked, stop for a moment and then resume as soon as possible.

If the screaming is working as it should, the other offense will show signs of "snap strain".  You will recognize this condition when the offense is just at the line, poised for the play for an inordinately long period of time.  Often, the quarterback will being to look over toward the sidelines.  The linemen's buttocks may tend to sag slightly lower to the ground.  You will see the center fidget with the ball and his knees may bend an extra time.  The quarterback may seem to strain his neck somewhat.  Eventually, he may back away from the center.  If all is unfolding as it should, it is absolutley critical to increase the sheer volume of your scream and hold it there for as long as you possibly can. One of two things will happen next.  Either the quarterback will call a time out or better, a delay penalty will ensue.   There is nothing better in the world than the feeling one gets after executing a proper scream and one sees the timeout signal from the opposing quarterback.  Nothing, that is, except the beautiful sight of that fluttering golden yellow flag flying in a perfect rainbow across the gridiron.  At this moment, all is right with the universe.  You have successfully made the transcendant leap from spectator to participator.  You are not a mere fan, quitely waving a pom pom while counting out change for another personal pan pizza.  No.  Now, you are the fanatical equivalent of a Gator player.  You have changed the outcome of the contest.  Most importantly, you have done your part.

After the Gators have won, while wildly slapping high fives and downing the last of your 80 degree bourbon and coke, quietly slip a lozenge into your mouth and smile.  You did it.  You got loud.  And you reclaimed The Swamp. 

Where only Gators get out alive.
