Fuzzle - Verb.
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.
