Yo mama so fat!
She sunk the Titanic. She put on a blue coat and they thought she was an iceberg!
Alright, listen up, buttercup. This joke is all about how ridiculously overweight yo mama is. Like, so fat she's mistaken for an iceberg and even managed to sink the Titanic! I know you are not smart enough to understand, so I will remind you that Titanic sunk in 1912. Do you even know when was that?
