Yo Mamma and Red Bull

Okay, listen up, smarty-pants! This "yo mamma" joke is saying your mom is so dumb she thought Red Bull would give her wings and let her fly off a building. Get it? Red Bull's slogan is "gives you wings," but it's just advertising, not a magic potion for you dummies. And, by the way, I heard you still believe in the tooth fairy, you big goof!
