To lightly rub the fingertips back and forth across another's head as a gesture of affection. Babies and sweet, old grandmothers are perfect recipients of a fuzzle. Not to be confused with the noogie, which is done in in a violently playful, or derisive manner and with the knuckles. In the fuzzle, the fingertips are placed just above the hairline. If the person is bald, the fuzzle becomes a "tappate", and is then done by very lightly and briefly drumming the fingers on the head. Either the fuzzle or tappate is usually finished off with a smooch to the area.
"Be sure to give gramma a fuzzle and a kiss before you leave".
