Acronym for “Pain In The Butt Unless Liberally Liquored”. Refers to a whiny spoiled-rotten individual who exhibits selfish immature “canine” tendencies (making lots of noise and creating messy chaos, getting underfoot and wanting constant attention when others are busy, sniffing and nuzzling everyone continuously, etc.), and whose disruptive behavior subsides only at times when he is totally passed out from excessive alcohol intake.
