The Tibbe test is a test one uses to measure the thickness of a penis by using a toilet paper roll. You simply try to put your erected penis through the hole on the toilet paper roll. If the penis stops because of massive girth, you have passed the tibbe test and you have the penis of a champion, girth wise. If the penis goes right through, you have failed. And if the penis doesn't stop, nor comes out the other end, you have failed in an epic way.
Roy: So bro, did you pass the tibbe test?
Steve: Yeah, I had no chance getting my beast in that thing. It stopped right at the beginning.
Roy: Wow, you must be really well hung, a real BWC.

A test you give a girl to determine whether or not she's old enough to have sex with. Basically you sit her on a curb, and if her feet touch the ground you're good to go. It's really just a joke...nobody has ever been known to actually use this with the exception of R. Kelly.
Until Aaliyah could pass the curb test, R. Kelly had to settle for a good ol' date with Jill every night.

Phil's date was beautiful, but she had a deep voice, so he decided to do a unit test before he kissed her.

Any coming test, college, high school, or middle school, that you know you will do/have done well or exceptional on. This test is a safeguard for the other test/paper that you know you will to poorly on. For absorbing the shock of when you get a 73 on your term paper.
Dude, I think I'm set for the end of the year; I got a ninety on that history test, and I'm thinkin' that's my buffer test for that hugeass paper we have to write for Smith.

Listening to Lil Wayne's bass-heavy song "A Millie", in order to test out the bass on new headphones or speakers.
