Mexican Shotgun 

After eating a large amount of Spanish food and while life is fine and dandy you get the "Oh, no" face. And abruptly leaving the table, running to the restroom. Making it to the restroom gliding across the floor as to not have any impact. Once in the stall, you fumble with the pants forgetting how to unbuckle pants as if it were the most impossible task.
Great Success.
Then taking pants and underpants off at same time, once they hit knee area, fully expecting to make it to ankles. But unexpectedly once at the knees, your poor lack of timing causes your tightened sphincter muscles to release. Your only course of action at this point is to attempt sitting before your poop spray coats the walls. But alas, it is too late. There is now a shotgun blast of poop starting on the walls waist level leading to inside the toilet bowl. You continue to finish all of your amazingness into the toilet. After the sweaty unfortunate event, you wipe up your butt as opposed to your neighbors, picking up your pants and leaving the restroom in shame. Anyone else entering the restroom will know that the last person to use this stall was the victim of a mexican shotgun.

I totally Mexican Shotgunned the Denny's bathroom. There were no survivors.

Mexican Shotgun 

After hitting a marijuana related item, before exhaling, allow a friend to push on your chest with your back flat against the wall. Hold your breath while they are applying pressure, then once you need to breath signal them to let off. Once you exhale, the oxygen traooed in your lungs will race to your brain cause a system overload kinda. In other words super high super fast. Warning - you could possibly black out, have someone their to catch you.

Dude, I gave someone their first Mexican shotgun and they were slumped!

Royal Mexican Shotgun

Noun- The act of draining a Corona beer in someone's ass, and then sucking it out as hard as you can. When the person getting thier ass sucked is ready, they will push (as if taking a shit) and "shotgun" the rest of the beer into the drinker's mouth.

During the exciting study group, Martha pulled out a thirty-six of corona, and we decided to take Royal Mexican Shotguns from her ass. During my turn she pushed to early and my chest and mouth were covered in beer and ass juice.
