A term used to define when someone attempts to give a fist bump and the other party was trying to go for a hand clasp, resulting in a slightly awkward but majorly homo gesture in which one person is softly "cupping" the others fist.
Girl 1: Did Daniel just fist that homeless guy?
Guy 1: No, that's effing gross. He fistcupped him.
