To exit or depart (from some place) in a quiet, sneaky, inconspicuous, or furtive manner. The would-be burglar slunk out of the house after hit the alarm. 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 heart to watch the losing team slink out at the end of the game.
