Bingo!

In law school we played a game called B.S. Bingo (I hear they play it in boardrooms too): imagine a bingo card-- except, instead of numbers, the squares were filled with overused catchphrases or buzzwords. You would mark off a square anytime one of the words or phrases on your cards was said in class. If you completed a row, you'd say (or cough) something that sounded like bingo.

I haven't seen a B.S. Bingo board in a while but if I were playing with my friends and we were goofing on ourselves (as we often do), these are the kinds of things that would fill up the spaces on our boards:

"wait-- what was I talking about?"

"Do you see that I'm on the phone?" (said to a child)

"That's ridiculous"

"That's awesome"

"It's driving me crazy"

"I couldn't believe it. Can you believe it?"

"Why would anyone do that?"

"Are you serious?"

"Are you kidding?"

"I don't know why but I'm so tired today"

"Coffee?"

That last one would have to be the "free" space.
