The missionary trap
The act of attempting to smack/hit the light switch as to avoid eye contact while participation in the sexual position known as ‘missionary’, but since you are locked in a perpetual state of kissing and smacking, you are forced to awkwardly look away at other objects around the room while trying to maintain an erection.
Yeah dude, last night I was banging this hot chick, but then I had to bail since I got into the missionary trap, my dick went limp almost immediately!
