A sex act in which the tip of one's penis is injected with a substance, i.e. heroin.
First referenced in The Daily Show with Jon Stewart on May 8, 2006, it was humorously linked with the bureaucratic reshuffling occurring in the CIA.
During the orgy with the Thai hookers, Jon got a Carlsbad Grimple and was rushed to the hospital as a result of an allergic reaction to the heroin.
