Yo mama so old.
Her first Christmas... was the first Christmas!
Alright, listen up, buttercup. This "yo mama" joke is all about exaggerating how old someone's mom is. Like, so old she was around for the very first Christmas, ya dig? It's like saying your grandma remembers when dirt was invented. You probably don't even know what Christmas is. Sad.
