look up any word, like the eiffel tower:
SMUFO is the ad libbed acronym for the Sunday Morning Union of Fun and Orgasm, a spontaneous event that has become an institution.

Smufo is an ancient human activity, that some behaviorists have noted occurs throughout the natural (animal) world. Until recently Smufo was an undefined act of physical bonding between two humans (animals) involving touching, holding, fondling and other tender physical ideas that popped into either the Smufee's or Smufor's head.
After weeks apart, Uma looks forward to some serious smufo activity with her lover, Groper.
