A small town overrun by cops that have nothing better to do than to harass innocent teenagers trying to have fun. Instead of helping Vallejo where actual crime is happening
American Canyon Cops:
Cop1: hey I'm tired of sucking your dick

cop2:yea! i dont wanna help Vallejo, I'll get shot!
cop1 and 2: Yay!!! we're pussies!
