RP 

The penis of the ambiguous figure called no-face.

It all started in a skype call. mid-2009 when no-face flashed his penis in the conversation topic picture.
Everyone was enraged and surprised.

Thus, RP is associated with the ambiguous No-Face or someone else who has a picture of his penis luring a group into a false sense of security and then surprising them with No-Face's penis.

Exmaple 1: I just RP'd Kaitsu at class today.

Example 2: I got RP'd by Kevin today!

RP 

Short for roleplay, something that socially inadequete people do because they're too scared or socially-inept to interact with people in the real world.

RPer: Want to RP with me?

Me: If by that you mean, "Have another reason to avoid interaction with another human" then no. I'd rather talk to someone in the flesh.
