A really sexy guy on a T.V. show called happy days
the fonz usually says "Aaayyy" while sticking his thumbs up in the air. He also is able to attrackt women by snapping his fingers and can start the juke box by hitting it
one who wears a white shirt under a leather jacket, walks around with his coller up, clicks his fingers, and points with two fingers of each hand at a time while saying 'ehhhh!!'
Much like the Dino Spumoni, The Fonz is when you catch two people off guard and shove both of your thumbs up the said persons rectums and shout "Aaaay!"
"Kathleen and I were talking in the common room when Mike came out of no where and got us with "The Fonz"...now I have a restraining order against him."
