Brag race

One person makes a boastful statement, and then another does the same in an effort to outdo the first.
The "Brag-race" is now on.
Whoever runs out of brags first, looses.

I was at the bar last night.

Stan started talking about this hot blond he nailed the other night, and then Mortimer chimed in, trying to out do him.
The Brag race ended in tears when Stan forced Mortimer to confess he was actually talking about an incident with his own cousin at a family reunion.
