An insult used to describe someone who gobbles down shlongs at any opportune moment, oftentimes completely randomly and in awkward places (such as, on the school bus, during you parents dinner party, while you're performing at the talent show). However, the BJ will always be extremely sloppy, to the point where it isn't even enjoyable. Your orgasm will be VERY unfullfilling.
'Ayo, I was performing in my mixed pairs figure skating competition, and then in the middle, my partner pulled down my tights and gave me a sloppy blowjob. I squirted on her face..but, I was really unfullfilled after.'
'Word, that bitch was an Expo'
