We like to yell at the end of our first mvt.
"The Christians are Gone!" since they mvts. called the Rapture

oh, and we always tell our tenor to stop banging and playing dirty "muted rimshots"...or skanks

Our instructor tells us to play with cajones....snugglebunny.
Especially to our female players.
Its funny as can be.

At a sectional we use the classic 'shoes in a dryer', and 'dirty trash can full of POOOOOP' (accent on poooooooooop).
Im sure once summer tour starts i will hear so much worse.
XD

Haha, yeah, we had two females on the line a few years back, and the instructor would say something about playing with balls then he'd give a suspicious look to the girls

I always tell the girls to "Hit it like a man!" and use a really heavy southern manly accent..

and then they yell..."Were not men!!!!!!"

"fold"
"stock"
"super fold"

nuff said.

One of my favorites comes from John Campese. When he would come in with revisions to the book he would say "here comes the fireman", ready to water down our parts if we didn't get it clean.

A few of them:

"We're going to state!" - Sam Houston State University drumline.

"Music is not hard. Bricks are hard. Music is time-consuming." John Lane, percussion prof. at SHSU.

"you gotta play with some sac" -Darren Hazelett of the WCU Drumline

Hms drumline....We got crabs
save a drum beat a drummer

"Don't flark up"

That's some pretty good advice, think about it before a performance some time :P
