A smelly taco is slang for a vagina that smells of cheap taco seasoningand the unfulfilled dreams of unbaptized orphans.
Hey Steve, have you ever smelled Jane`s vagina? In my classification handbook for vagina scents, similar to a handbook for animal tracks, it is most closely related to the smelly taco.
When a Mexican guy (always male) smells like either. A bad smell of tacos or a weird smell of tacos when I personally smell this I think I'm racist for a second then sniff again and sure enough I'm right my dude.
