Just about. The greatest comeback to anything. Used mainly when talking about the size of genitals, but can apply to anything else.
Person A - Hey look at our science. That's bigger than yours!
Person B - That's not what your mom said last night!
Person C - Oh BURN.

The one and only appropriate response to the age old saying "you smelt it you dealt it" thus pinning the flatulence back on the gentleman whom is most likely responsible.
*gentleman 2 farts in the elevator*
gentleman 1: Oh my god that smells disgusting! Taco Bell again for lunch?
gentleman 2: Dude...you smelt it you dealt it
gentleman 1: On the contrary, you said the rhyme you did the crime
gentleman 2: You reversed the charge so your at large!
gentleman 1: umm no...that is a stupid one
gentleman 2: damn ok you got me

tell your man i said boo

this is usually said by a cheating partner as an inside joke to the person he or she is cheating with. it is meant as a joke about popping up and saying boo to the cheating partner's significant other, which obviously can't be done.
"tell your man i said boo. when are you going to leave his broke ass for good so we don't have to sneak around anymore?"

Can ONLY be countered by "if i wanted a comeback, i'd wipe it off your chin"
Protester: Your bloody war has killed hundreds, if not thousands of people, destroyed countless amounts of property, and has made your country the most infamous in the world, all in the name of preserving America's oil interest.
Republican: .............. THAT'S WHAT YO MOMMA SAID ABOUT YOU!
Protester: Well you got me there.

similar to that's the sound your mother made last night. it also originated from SNL celebrity jeopardy. it was said by Sean Connery and is just another sexual innuendo.
Sean Connery: It's been a long time, Trebek.
Trebek: Not long enough.
Sean Connery: That's not what your mother said last night!
