The Zesty Mexican is when you dip your cock in spicy salsa, then proceed to cram/jam your penis into an anus while wearing a sombrero. You may also include the option to yell O'ley while performing the finishing move.
Man: Dude, I gave my girlfriend the Zesty Mexican last night!

Friend: Dude, bro, that's bangin'. Have you tried giving her a hot lips houlihan?
