A scatalogical sex move wherein
one partner assumes the
lobster position by squatting over another's open mouth, makes claw-motions with their hands, and defecates into their partner's mouth. It is usually courteous to return the favor.
An alternate but rarely used form known as the Squat Rock Lobster exists, where the lobster-partner sticks small rocks (pebble-sized) up their anus beforehand to pelt their partner with as they shit. This satisfies both
scat fetishes as well as
pain/torture fetishes, and as a double bonus goes great with the B-52s' single Rock Lobster.
Mark: So, did you hook up with Jessica last night?
Kevin: Yeah man. I gave her the ol' Squat Lobster as a finisher.
Mark: Didn't...you go out for
Mexican last night?
Kevin: That may be why she hasn't called back.
