When having sex with a female, first, place one of your thumbs in the ladies vagina. Next, place the other hand's thumb into the butthole. When both thumbs are securely into the females body you end it (and probably your night) by saying AAAAAAYYYYYYYY!
The other day I stuck my two thumbs where they didn't belong and I did The Fonz. She ended up kicking me in the balls.

Giving a girl "The Fonz" refers to the act of ejaculating onto her face, then gesturing with two thumbs up and proclaiming the happy-days catch phrase: "Ayeeee"
