It means your mom but you know some people are fucking lazy (like myself) and don't feel like typing that much.

when you're hungover as shit after a spending a night drunk as a skunk

YO TOMAS!!!!!!!!!!!!!

A shortened word for yo mama when you are lazy

Contraction of "your ma"

Yomas is a male name most commonly used to for a hadsome, smart, attractive and most importantly big dick sized dude. Not alot of people over time have had the right to be called Yomas. However there is a legend that some awesome mofo located in the middle of Norway might be the last remaing Yomas.

If a Yomas happens to take a liking to a girl, it is known as a fact that he will get pussy that night.

Girls also tend get their pussies soaked whenever looking at a Yomas from below. If a girl were to look at him from above, the female would transcend to heaven and become a beautiful angel. The last claim is curretly being investigated by highly trained pornhub.com investigators to only be a myth, and it also makes so sense at all...

If Yomas says your waifu is thrash, its not just his opinion, IT IS FACT.
