The act of pulling one's penis out of a woman's vagina while simmultaneously releasing one's balls from her anal cavity. This in turn makes a suction sound that can quite humorous. The maneuver resembles a lobster (the woman) being caught in a trap (the man) and not being released until the man blows his load and his balls decrease in size allowing the removal from her anus.
