What is Mexican Hotplate?
When you take a hot pepper, rub it all over your lips... Then proceed to go down on your woman....
Pre-requisite of being 65 years old plus. When younger than that, it's called being an asshole and is only performed in secrecy without the woman's knowledge.
Old woman: "I just love it when you kiss me 'down there'. You're like an arist with your tongue."
Old Man: "pass me one o' them hot peppers"
