A term used to describe anal sex. A guy penetrates (sticks) a butt (back). It is used to disguise the dirty words usually describing this action and is often used when (normally heterosexuals) are humorously speaking about anal sex.
Did you backstick that chick last night, Hermie?
- Yea, haha! I got in, went for it and dug in real deep.
