In Europe, it is in many countries the short form of fashist.
In Germany, for instance, "ein Fascho" translates to "a fashist", or "das ist aber fascho" (eng. "that is so fashist"). Even Google Translator translated "Er ist ein Fascho" into "He is a fascist", and equivalent to "fascho" (adjective).
It is, however, not related to the AmericanBlack slang of "fasho" as "for sure".
That was so fasho.
You are a fasho.
That party is fasho.
A past tense of the word "eat", or more specifically "eaten". Taking the d
incorrectness of et further than it's ever gone before. Used by illiterate and/or bored Southerners out of ignorance or good 'ol plain fun. Try it out on a Northerner and see what they say.
