Question: What is a "butt whoopin"? I heard a shabbily dressed woman in the supermarket yelling this to her son..is she going to whoop it up in the region of his buttocks or what?

Answer: it is a product that straps onto your chair, sends thumping vibrations through your seat, and rattles your rump and your brain as if you were on top of a giant loudspeaker.
