When a guy lays face down to a bed and starts producing friction between said bed and his junk. Used at times in public spaces when said guy is horny and fakes being tired in order to bedsturbate.

"Dude, we were talking about this hot chick in our hotel room and I got the hardest boner ever"
"And, what did you do?"
"What d'ya think? I bedsturbated.."
