Misfeeding refers to the accidental penetration of the anus after getting over excited during sex in the doggy style position.

Misfeeding tends to lead to a bad mood for the receiving party and has in some cultures been nicknamed "death sentence"

Misfeeding must be accidental. On occasion there may be a near miss where penetration is not acheived and the anus is not breached. This is known as a rectal bounce.
