used as a comeback for when your friend is hitting you with a your mom insult
weirdly effective
Person 1 : your mom is fat!
Person 2 : YOUR MOM IS YOUR DAD
Person 1 : ..... (can't come up with a better comeback)

Get the your mom is your dad mug.
"your mom is your dad's mom" is a satirical reference to jokes beginning with "your mom is..."

it came from boredom while walking around target.

if someone is telling "your mom..." jokes, tell them this one, and you will win, for sure, i promise. they won't know what to say. guaranteed to work, everytime.
"your mom is so fat she......blah blah blah"

"your mom is your dad's mom"

"wtf?"

*clicks the thumbs down thing*
"yeah? well...your mom is your dad's mom"

Get the your mom is your dad's mom mug.
Phrase meant to rescue from any awkward situation and when repeated enough, makes people who take themself too seriously very angry. Most often used as an iron-clad comeback or avoidance of situation.
Bill: "Well, Obama's economic policy is complete crap, he's a communist."

Bob: "your moms your dad."

Bill: "Ahh...?"
