To leave or retreat in a quiet, sneaky, inconspicuous, or furtive manner. The would-be burglar slunk off after tripping the alarm. I knew the teacher wanted to lecture me about the poor results on my test, so I made a plan to slink off as soon as the bell rang. No matter who I'm rooting for, it always breaks my heart to watch the losing team slink off the field at the end of the game.

to creep away furtively. Carl was embarrassed and tried to slink off, but the ushers spotted him. The boys slunk off from the picnic and smoked some cigarettes.
