Mexican Shirt 

This is when someone is very fat, but just casually roams around with no shirt. This is typically a male of Latino descent when playing video games. To wear a Mexican Shirt is to wear no shirt at all and the only layer of protection is body fat.

Look at Aidan! He's rocking that Mexican Shirt lifestyle while playing Rainbow Six Siege! What a chubby guy!

Mexican Shart 

This is the Mother of all sharts. When you try to simply fart and power spray liquid shit which soaks through your underwear and runs down the back of your legs.

We all had to take a pay cut to keep our jobs. Then we found out the asshole paid his son in law a 9K bonus for being a summer intern. I ate a whole jar of jalapenos and sprayed his front door with a Mexican Shart! You can still see the stains from the runny shit!!
