P.I. 

Pussy-Itis, Puss-Itis, Pussy Itch. Being whiny and bitchy over a small, often imaginary injury.

Kid 1: Owww! You hurt my finger, I don't wanna play anymore.
Kid 2: Dude, you've got a major case of P.I.

P.I. 

The enormous fluffy gathering of hair above a man's lip in the 80s and unfortunately after the 2000 switch that resembles the actor Tom Selleck in his hit TV show Magnum P.I.

Dude did you check out that guys P.I.? That was massive!
Oh my god look at that man eat it's like he is storing food in his P.I. for consumption later!

P.I. 

Pleasure Island. The place where every night is New Year's Eve (how corny is that!). Owned by Disney but so not kid-friendly cuz you can get drunk, party, and have the night of your life.

If you've never been, check out Comedy Warehouse, Motion, and 8TRAX. They even have a gay club called Manequins. o_O

Just look for the tons of spotlights glaring in the sky, and a big neon sign of Jessica Rabbit.

"Some friend and I are goin to P.I. tonight, wanna come?"

P.I. 

Short for the Philippine Islands. The Philippine Islands is the colonial and derogatory term for The Philippines. Popularised by American G.I.s from World War II, and after the war. Currently still used today in North America

My parents migrated from the P.I. in the 80s. I am lucky not to be an Islander anymore
