this is accomplished by making a surprise-dry run at a females anus.

This cannot be a simple push in, you must be at least two steps behind the female and, she must be taken by surprise AND cry afterwards.

Very similar but not to be confused with "the Dirty Sanchez." The Dirty Tebow is when you're doing anal, pull out and instead of drawing a mustache above the girl's lip you draw a streak under each of her eyes. The result looking like she's wearing those dark things Tim Tebow puts on his face on gameday. Writing a message in either streak is optional.

When a person (man or woman) Tebows and then furiously begins to masturbate with their right hand.
