Slack-Jack 

A complete and utterly terrible handjob. One that is simply not worth the time and honestly makes one wonder what the fuck is wrong with with the human being who's head is in your lap.

Brady came back Jones' house and told everyone that Liz gave him the Slack-Jack of the century and he'd rather stick his dick in a pinecone than experience that again.
