That's not what your mom said last night 

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.

That's Not What Your Mom Said in Bed Last Night 

A comeback that people say when someone says, " I bet you are terrible at sex." Or other comebacks. Then that person would come back and say, " That's not what your Mom said in bed last night."

Guy #1: Your dick is probably the size of half of a raisin.
Guy#2: That's not what your Mom said in bed last night.

Last Night Was Great 

A lie told to a partner the morning after underwhelming sex. It can also be accompanied by: that was a lot of fun, you were great, we should do this again, I have to go to work and I’ll call you .

“Wow last night was great, but I have to go to work.”
“Will I see you again?”
“Yeah I’ll call you.”
