Random kid: Yo mama so stupid that she brought a spoon to the Super Bowl.
Orphan: What's a mama?
Random kid: *shook*

Listen up, buttercup! The joke is about an orphan not knowing what a "mama" is. The first kid tells a "yo mama" joke, but the orphan's reply totally throws him off because, you know, orphans don't have mamas in the traditional sense. You probably just learned what an orphan is. Congrats!
