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!"
