groin-grabbingly good

A term used to indicate extreme pleasure with something (it could be practically anything), to the point of that something inducing the grabbing of one's genital area in a reflexive attempt at masturbation. Not necessarily literal. The term was coined by television buffoon Homer Simpson.
