During intercourse, one partner grabs a lobster that had been previously concealed somewhere close by and slaps the other person/persons across the face with it.
This technique usually does NOT result in an orgasm for anyone but the lobster.
Rubber bands on the claws are optional.
man 1: "man, i was with this fox last night and she told me she has a difficult time reaching orgasm."
man 2: "don't use the Northern Somalian Lobster Slap! it doesn't work! and if you do, make sure to use rubber bands on the claws. my wife made that mistake. once."
man 2 points to where his left ear used to be.
