Meaning first-class or grade-A. Often used before an offensive word to emphasize the magnitude of that offensive word. Words that could follow A1 include but are not limited to: cunt, bitch, and slut.
After Sally, the puck-slut, blew Todd and the whole hockey team, he slapped her with his hockey stick and said "Sally you're an A1 bitch!"
