Mexican toilet 

(or shit bucket).The practice of using the restroom in a bucket with a contractor bag in it as a liner as to not ruin the bucket for later use while on a construction/demo site when there is no Porter potty or running water on site.

Damnit! There ain't no water on and no Porter..and my stomach is Killin me. And the gas station is too far...

Mexican Spicy Toilet Nuke 

When you go to a mexican restaurant who serves general mexican food with a lot of creamy stuff and chicken and cheese combos and you go to the toilet and take a spicy almost constipated diarrhea that literally burns the asshole for hours after, if your lucky you might take a giant shit and literally nuke/murk the toilet with your feces where you might need more gallons per flush

Guy #1:Dude I need to take a major shit
Guy #2:My house only has 1.5 gallons per flush
Guy #1:Ill need about six this is a Mexican Spicy Toilet Nuke
