ninjafuck

To have sex in a bunk bed without your bunkmate noticing.

Dude, I ninjafucked this girl last night. My roomie had no idea. I guess he likes being rocked to sleep.

ninjafuck

If I heard this right, it refers to the action of being sexed half-willing, whether out of obligation or whatever motivation (this isn't referring to rape, mind you). It comes from a movie called Dog Park, and I'd like to see the term used more.

"How'd it go last night? Well, she ninjafucked me."
