1. One who double parks his drinks, afraid to have to wait go wait on queue again for a drink (because he's a bloody fast drinker... and an alcoholic). ie like, multi-tasking.

2. A borderline alcoholic who lines up more than one drink at a time, sometimes up to 4, so as not to waste time queueing up.
