Sweaty Mexican recipe

I've seen ladies give this shot to chaps who won't take the hint to go chase themselves. But where I'm from, they float a dollop of mayonaise on top and it's known as a "Greasy Mexican".

This is a variation on the Sweaty Mexican made popular as a coming of age rite of passage shooter in Geneseo NY at the infamous I.B. (Inn Between) by the Royal Order of the Orange Knights (aka, The Pigs). When you turned 21, and you were a Pig, you had enough of these to make you hurl them all back up before the night even began...I believe 12 was the most I had heard of for a single sitting, and that was not pretty - the variation is, same drink with an extra 2oz of Yukon Jack mixed in for growth and good luck...
