your mom's mom 

A comeback for someone who has run out of comebacks. Usually in response to "Your mom."

-Your mom!
-... your mom's mom! Shut up!

Your mom’s mom’s mom’s mom 

A godly level roast that will leave the person dead.

Jimmy: I was eating your mom!
Bob: Well I was eating your mom’s mom!
Jimmy: Well I ate your mom, your mom’s mom, and your mom’s mom’s mom!
Bob: Your mom’s mom’s mom’s mom.
Jimmy: *freaking disintegrates*

Your mom's mom's mom 

The insult used after "Your mom" and "You mom's mom" have already been exhausted. It is often used by small children that do not grasp the full scope of comebacks.

"Hey Timmy, want some apples?" "Your mom eats apples." "Your mom eats my dick." "Your mom's mom eats my dick." "Your mom's mom's mom eats my dick and drinks my cum! Oooooooh!"

Your mom's mom's mom's mom's mom

An exruciatingly destructive insult to leave a person destroyed. It's the most feared comeback of them all, even more so than your mom's mom's mom's mom. This insult even leaves the user gasping for air.

The item dropped after such an insult is the ashes of the ones unlucky enough to be on the recieving end of it.

Viggo: I ate really nice squid last night.

Hans: Yeah well, I ate out your mom last night.

Viggo: Well, I ate out your mom's mom last night.

Hans: Oh well, I ate out your mom's mom's mom last night.

Viggo: That's nothing cuz I ate out your mom's mom's mom's mom last night.
Hans: Too bad, for I ate out your mom's mom's mom's mom's mom last night.

Viggo: *Combusts in fiery flames*

Item drop: * Ashes of your enemies*
