He was no bar fly but he did have had an awful lot of alcohol at his house.

When a girl and/or guy are in a serious relationship but they are overly flirty with others.
All these married bar flies are swarming the guys at the bar.

at last call the bar flies practically swarm every female in the room, so they can bring a piece of ass home.

A species of botfly that is attracted to the scent of alcohol. Its life cycle is similar to the botfly, however, the barfly lays its egg on the skin of unconscious drunken patrons in bars and clubs. Once the maggot is hatched, it bores into the skin of the victim and develop over the course of 6 weeks while feeding on the victims flesh. It then pupates and develop into an adult in another 2 weeks, the adult then fly away. The bar fly has been known to excerbate the effects of a hangover
"Dude! Shit man, a barfly must have laid an egg on you while you were passed out! There's a maggot crawling out of your arm!"
