Short for "Danny Tanner." Used to describe a fellow who spends a lot of time at home cleaning it. Often times D.T.s will clean for a place to stay.
Hey, me and my girls shit on the floor, ate hot dogs all messy-like and had our periods all over. No worries though, this bitch ass D.T. will have it cleaned by sunrise.
