look up any word, like sapiosexual:
This stands for P-E-N-I-S..As you can see the 15 at the end of pen15...the 1 resembles the "i" and the 5 resembles the "s". Lots of grade schoolers ask about, "do u have a pen15?" they say that its a pen, so when they say "no" they start to humiliate the person. This is a very imature act.
Yo sup? hey do u have a pen15?
WHAT?!? whats a pen15

An old grade school prank. You'd write Pen 14 on your hand and walk up to an unsuspecting schoolmate and ask him if he wanted to join telling him he could be Pen 15. You'd then write Pen 15 on his hand, and everyone would laugh at him.
"I'm in the Pen club. I'm Pen 14, you can be Pen 15."
