Flat tiring someone is when one man jerks another man off until he is no longer able to become erect for a certain period of time.

When a female/male is riding their partners face, and on orgasm they defecate on their partner's forehead and flatten it with their ass cheeks.
Marry was riding my face so hard and gave me the largest Michigan Flat Tire that I'm still trying to wash it out of my bangs.
