Mexican Castration 

...can happen as a result of carrying Mexican i.e. sans pistol holster/proper retention device--gun usually tucked into waistband.

Literally: to accidentally blast one's own genitalia off via a negligent discharge of a firearm that is being "carried Mexican."

Mexican castration almost happened to Plaxico Burress when his (.40 S&W) Glock 23 went off and struck him in the thigh at that New York night club because he had his piece tucked into the waistband of his sweatpants. But seriously, despite the fact that he could have shot his own balls off, who wears sweatpants to a nightclub?

Mexican Mortar Strike

Filling a sock with fresh crap that you just took and launching it into the air at an unsuspecting group of people. Must be launched in the air at a decent height. Works best after a night of heavy drinking and eating spicy food.

The people next door were being too loud at night, so Monty decided to launch a Mexican Mortar Strike on them.

Mexican Tap Water 

A beverage consisting of 1 part Corona, 1 part mule piss, and a generous portion of tequila. Serve in a quart glass, rimmed with cocaine and a wedge of sod.

The tradition of rimming the glass with cocaine began as a trick by bartenders so as to counteract the effects of the massive amounts of alcohol in the Mexican Tap Water. The cocaine would keep the customer from passing out, allowing him or her to keep drinking.

To penetrate a lady from both ends simultaneously, ie orally and either anally or vaginally, whilst both male participants wear sombrero hats to protect the lady from the glare of the midday sun.
