An always-stiff-penis. A penis of such small stature, it fails to have the length to hang down, hence, being always stiff.
Also known as, an Always Stiff "Peeper," rather than penis.
Example: I was changing in the locker room today with the guys, then I looked of at Tommy, an he was sporting a tiny dick, possibly an A.S.P (Always Stiff Penis).
Example: Dude, after I banged her, I took a cold shower, and came out. She threw off the towel because she wanted to give me head. She looked up and said, where'd it go? I must have an A.S.P (Always Stiff Penis).
It also stands for All, Sine, Tangent, and Cosine. But All Students Take Calculus works as a great mnemonic device.
Teacher: Any ideas for mnemonic devices to remember A.S.T.C?
**Class stares blankly
Teacher: Well, the way I learned it was All Students Take Calculus. There is also this really nasty one that I can't tell you. And if you figure it out and said it aloud I will give you a detention!!
Student A: Tell us please!!!!!
Teacher: No, I don't want to lose my job.
**10 minutes passes
**Student B turns to Student A with a calculator and a little piece of paper in it. Student A Opens this piece of paper and it reads:
"A.S.T.C. - All Sluts Take Cock - I dunno if this is right but I tried"
**Student A Breaks out into laughter and falls out of her chair.
