That's what your mom said 

A clever combination of "that's what she said" and "your mom!". It was created to avoid the argument that "that's what she said" creates confusion because "she" is nobody while adding the punch of "your mom" jokes to it.

The phrase "last night" may be added to the end if extra pwnage is needed.

Person 1: "Whoa, that's a big hot dog"
Person 2: "That's what your mom said!"

That's a pertty mouth on you, boy.

phrase. Originating from the movie "Deliverance", when you hear this, run. Apparently, you've just pissed off some country bumpkin and he's about to ass rape you. Nice going, city-slicker.

This phrase is more often than not followed by "I'mma make you squeal like one o' my pigs!"

You: Hey, you ain't got no teeth, so no dental records, and yo mama is yo sista and yo aunt and yo grandmama! Just like all of 'em! How can they tell you apart from the rest of them country bumpkins???

Billy Bob Joe Brown: That's a pertty mouth on you, boy...

You: What's that supposed to mean?

Billy Bob Joe Brown: *points gun* Drop them britches, son.

You: Um um um ok...

Billy Bob Joe Brown: Imma make you squeal like one o' my pigs!

You: What's tha- WRRREEEEEEEEEEEEEEEEE!!!!

That's what UR MOM said 

A "UR MOM" come-back but more rad. It then continues to "that's what SHE said" if necessary.

boy "I wish I saw you in a thong..."
girl "That's what ur mom said!"
boy "oh my God... Jesus."
girl "That's what SHE said!"
boy "wait, who said it?"
girl "ur mom"

that's what your mouth says 

A way to tell someone you don't believe them, or to say they're full of shit.
