Mac Hall - To have a Mac Hall is to go nuts and kick your leg like you'

To have a Mac Hall is to go nuts and kick your leg like you're fighting a ghost while everyone stares at you.

My roommate had a Mac Hall in the dorm. He kicked his leg so hard, the door flew open and a rat ran out.

I had a Mac Hall in the middle of the night. I kicked my leg, screamed at the wall, and then fell asleep on the floor.

During my Mac Hall, I kicked my leg so hard, I woke up my neighbor and he thought I was having a seizure.
