When your dick is too soft to put it into some chicks pussy, so u gotta fold it and stuff it.
"hey babe, I can't get hard. I'm just gonna fold it and stuff it."
When your having sex with a girl and you cant get it up but your too lazy to jerk off. You fold it, and stuff it!
"I'm sorry babe, I can't get it up. I'm just going to fold it and stuff it!"
