The mixture residing in the anus of a Mexican male who recently had his anus ejaculated into, whilst carrying a scat baby that is ready for delivery, the other Mexican male then takes a straw and drinks the combination of both the twice digested scat baby and his own recently secreted (into his homosexual partner's anus) seminal fluids.
More recently Mexican Cocktail Sauce has been smeared in the form of swastikas (often mistaken for refried beans) on Arizona Government buildings.
Ooooh Pedro make sure you save some of that Mexican Cocktail Sauce for our Tostadas. ARRIBA!
You know it pappy, I'll make sure I don't leave any by giving you some mean rim. ANDALE!
