look up any word, like hipster:
Someone who is so sexy it actually hurts in your pants when you meet her. Meeting a Tonni is like watching a sunrise from the moon. Tonni's are so beautiful they make beautiful people look not beautiful. When you see a hot chick and do a double take it called "doing a Tonni"
Mate she was hot....I did like a triple Tonni.
