Locked in the Box
The condition of a cock being stuck in a pussy. 
Man 1: dude, my cock is soar as hell!

Man 2: damn, I thought you said you hit that shit last night. 

Man 1: I did, man, but I got Locked in the Box so I had to spray my jank with a water hose to get that shit out. You know how spring cock will swell up on you.
