secretive, sneaky, stealthy (from sleuth)
after I got 86'd I had to be sloof
by Joel Mitchell November 18, 2003
one who over reacts to a joke,quip, or any innocuous trifle by holding a grudge with the perpetrator for a long time.
That sloof doesn't talk to me anymore because I laughed when she chortled; the was six months ago.
