Stands for Pretty Small Penis. Sometimes used by elementary school boys to mock their friends, who think that they are referring to the PlayStation Portable and thus results in a hilarious conversation.
"Hey man, were you playing with your P.S.P. last night?"
"Yeah! I got the new model! It's even smaller than the original!"
"*snickers* Good for you..."
