When your banging your partner and then soon you start shoving your penis into her anus, and you try to shove it until it touches her sphincter, and then after minutes of shoving, you cum a painful stream into her anus. Named after the aerial stunt from MLP: FiM.

A sh!tbox car is one that is worn out car that is falling apart, litterally leaving a trail of parts down the highway.
The sonic part comes from the fact that this car is equipped with a fart cannon muffler. the term sonic sh!tbox usually implies that the car is eurotrash.
