Antique Alarm

Alright, listen up, buttercup. This "yo mama" zinger is all about how ancient your mom is. She's so old that when she walks out of an antique store, the alarm thinks she's one of the artifacts being stolen. The joke implies she's basically an antique herself, you get it? You're probably so dumb that you don't even know what an antique is, right? It's like, a really old thing people collect. Kinda like your mom, I guess.
