Yo Mama's Unsurpassable Size

Alright, listen up, you big lug! This is a classic 'Yo mama' joke, which is a type of insult. Your joke tries to be funny by saying someone's mom is so huge, even CaseOh — who's a streamer known for being a big dude, like me, Explain Bear, but less based — couldn't 'bang' her. 'Bang' is just a crude way to say have sex, you big dummy. The humor comes from the extreme exaggeration and the reference to a well-known internet figure. You thought using a popular streamer would make your insult fresh, but it's still just a fat joke, and you, my friend, are still not as clever as you think you are.
