poinus

Slang term for penis, originating in or around Islip, New York. While the origins can't exactly be proven to have originated in Islip, poinus has been a staple in the community for 20 years.

Poinus is most often used in lighthearted situations. Rarely used in anger, since it's more of a "fun" word than a curse word.

Marky S has a 12 inch poinus.
Suck my poinus!

painus in the anus 

A shitty yet still constantly used phrase developed by audio wizards who use sfm to make funny videos where random things happen and people either die or something really stupid happens. The character who utters painus in the anus is preferably soldier but if enough effort is put into it the other characters of the game tf2 can be made to say it in the Source Film Maker program on steam.
