1. When a surfer has the runs/explosive diarrhea and is waiting for the next set (of waves) too far from the beach to make it to a bathroom and "let's it go" while sitting on his or her board
2. A sex act where two wangs or sex toys are simultaneously inserted into a butt at angles so they come together in a point past the sphincter and the two wieners or dildos outline the shape of the front of a surfboard

Brodie was super embarrassed when he went back out too soon after eating Indian food and ended up with a rusty (surf)board.
I heard you and your buddy ran a rusty surfboard on your girl the other day. She must be super chill.

When a guy cums by gliding his dick along a butt crack, usually the bottom is laying face down and he is lying on top, no insertion, just an external prone bone between butt cheeks. Works for both straight and gay sex.

When you are at a party/large gathering, and you have to drop a poopie, so you proceed to turn on the bathtub/shower at said party, and proceed to take large poopie/poopies in the tub. Wait a few hours for the bathroom to flood, and vuala! A dirty surfboard!
"Yo bro I just rode the waves on that dirty surfboard you made in the bathroom. You pooed a fat one out."
