"Let's Go Have It"
If you were at the Pittsburgh Regional, you might have heard it. It is a bit of a story about how a team at a previous regional (which I wasn't at) was chanting something inaudibly, and we opted to poke fun at it with the name above.
Also worth noting, one of our team members was assigned the job of Safety Captain, and one of us coined him with the nickname "Safety Monkey", ala Penny Arcade. Well, throughout the entire regional, we all called him Safety Monkey for everything. Everything.
"Safety Monkey, I cut myself!"
"Safety Monkey, where is your gracious professionalism?"
And he even referred to himself in the third person, with the nickname.
"Safety Monkey didn't do that, now quit bothering him!"
