Get the mom battle mug.
Similar to a freestyle battle, except where a select portion of a sentence is integrated with the phrase, "your mom," and repeats back and forth between two 'your-mom-ers' until one runs out of variations before the other.
albo #1: is scott giving u a ride?
albo #2: giving ur mom a ride?
albo #2: riding ur mom?
albo #2: what what!!
albo #1: riding isnt a good choice to have a mom battle over too many nasty refrences can come out of it
