Dumb Yo Mama at Starbucks

Listen up, buttercup. This "yo mama" joke is sayin' your mom ain't too bright. She's so dumb she thinks she can buy an actual star at Starbucks, like the ones in the sky, not just a coffee. Which is dumb, since Starbucks sells coffee, not stars. And you, judging by the fact that you had to ask, probably ain't winning any smart contests either.
