smurf plunge

Sexual intercourse in a portable lavatory. As there is only room for one occupant, the head of the receiving party must be submerged in the blue chemical liquid.

Soldier 1: Why is your face blue?
Soldier 2: I was the second man in and had to take a smurf plunge in order to accommodate for the lack of fuck space.
Soldier 1: That's fucked up, but at least you got some.
