Butt bump describes a character swinging their hips to strike another with the side of their butt (also known as hip checking), or two characters forcefully pushing their butts together either from the side, or back to back.
Note: Do not tag this unless there is implied motion from the characters' positioning (see third example) or motion lines or emanata indicating movement and impact if there is no indication of motion, use ass to ass instead.
