A.S.P (Always Stiff Penis) 

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).

a.s.p (always stiff penis) 

1. a penis so small that it doesn't have the length required to generate hangage, giving the appearance that it is in a state of constant erectness.

2. Unit of measure based on the penis size of Wilco Jancala. One A.S.P is equal to one billionth of an inch.

1) I have to wear special pants so that no one realizes that I'm sporting an a.s.p (always stiff penis).

2) No dude, my dick is at LEAST two asp lengths.
