To exit or depart (from some place) in a quiet, sneaky, inconspicuous, or furtive manner. The would-be mugger slunk out of the house after I drew my pistol on him I knew the teacher wanted to lecture me about the poor results on my test, so I made a plan to slink out as soon as the bell rang. No matter who I'm rooting for, it always breaks my hear to watch the losing team slink out at the end of the game.
slink out (of some place)
to creep out of some place furtively. The fox slunk out of the henhouse just as the farmer came out. It slunk out and got away.
