After consuming several tacos a person vomits onto a woman's taint causing a lava like flow of vomit to gush into both the anal and vaginal entryways. Not to be confused with the Mexican trash can or Mexican dumpster which involve puking into the vagina or anus respectively.
I tried to perform a Mexican dumpster but misfired creating a Mexican landfill.
