The act of performing hot sweaty intercourse with a rotund Mexican chica who has been infected with every STD and then pouring nacho cheese in her vagina, inserting the males erect penis into the nacho cheese filled wizard sleeve. Then the male sticks his penis into the rotund Mexican chicas asshole while screaming "Ariba" "Ariba". After the Fiesta was completed the male inserts his nacho cheese poop covered dick into the rotund mexican chicks mouth, she then vomits all over the males penis and sticks it back into her nacho cheese filled vagina..while this is going on the male must grab a Sombrero while yelling "FIESTA"
Jim: Damn Jose you wriek like shit..did you perform a Fiesta Grande last night with Selena?
Jose: yeh homie but da nacho cheese didnt taste that bad.
