rusty surfboard

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.

Rusty Spittoon

The act of moistening the anus with one's saliva before having anal-sex/foreplay

1) I gave her/him the Rusty Spittoon, which really seemed to make things slide in easier.
2) Without the Rusty Spittoon, I would have felt like my dick stepped into the Majave Desert.
3) Who needs to do use the Rusty Spittoon when you have lube?
