The phrase itself is French banlieue style slang built for maximum disrespect, combining a crude reference to someone's mother with an image meant to sound physically impossible and absurd. Online, that excess is exactly the point.

Its popularity comes from recognition, timing and shock value, letting a single shouted sentence finish a joke without extra context.
