Top definition
An anal sex act, largely performed by males and females with strap-ons, that can be completed in three succinct steps.

1. Put it in the back door little cock-eyed ("a little cock-eyed" is usually described as at about an 80 degree angle).

2. Just leave it there for a little while (about 5 minutes is normal, but times up until 10 minutes or even climax have been done before)

3. Pull it out, and then look at the recepient of the act as if it's their fault (yelling optional)
