Okay, listen up, buttercup. So, the joke is that this dude is acting all casual when he sees his own mom, right? Like, "bruh"? And when she calls him out on it, he's all, "Yeah, no shit." Then BAM! Slap! It's funny because, like, who talks to their mom like that? Sheesh, you probably still live in her basement, don't you?
