Hairy Pineapple
The appearance of a man's scrotum through the mesh lining of revealing workout shorts or bathing suit; the mesh lining, or basket, mimics the diagonal pattern of a pineapple and allows the hair to poke out through the holes in the mesh.
When Schneider hoisted his leg up on the weightlfting bench to stretch his hamstring, I totally saw his hairy pineapple. Ewwwghhhk!
