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.
