A tradition in rural America, and the unisex term for a fish bump. (which refers specifically to vagina-equipped humans)

It's like a chest bump but at crotch level. It is not typically a sexually charged or intimate event.
Its romantic counterpart is referred to as a chicken kiss.
After throwing down a baller alley-oop, I chicken bumped my youth pastor. He almost got arrested but I told the cops that it wasn't a weird sex thing.

Get the chicken bump mug.
Typcially a young girl whose pussy resembles the bumps on a chicken breast once the feathers are plucked.
That girl is too young for you. She probably still has chicken bumps.
