Get the DadBalls mug.
The sport in which two grown men argue about their son being more talented than the other.

Originated on November 13th when two refrigerator magnets were formed to make the word "dadball". The creators then proceeded to rofl, literally.
The act of dadball:
Dad #1: "My son's in all honors classes!"
Dad #2: "My son's not a fat fuck!"
