noun; any sex involving multiple people with at least two Mexicans, one on each side
I went to this bar, and these two Mexican guys asked me if I wanted a taco, so I said yes, and they took me to their place to have a threesome with them.
Taco which is also know as a crush or someone you have feelings for it is referred to as a taco because it's your crush and taco shells get crushed easily when u mess up with them and your heart does the same thing
