Listen up, buttercup. This joke is playing on the classic "yo mama" insult format, but with a modern twist. It uses stereotypes and assumptions about gender and sexual orientation to try and be funny. Basically, it's saying your mom is transgender, your dad messed up his gender, and your brother is gay. Not exactly rocket science, is it? You probably laughed because you can't spell.
