Wey is a word used by mexican people that means different things. When you say it in a nice way it means buddy, but when you try to offend someone it means Jackass
The word "wey" is a Mexican slang term with many variations:
1)Informal "Que pasa wey?" Here meaning "What's up dude?"
2)Slang insult "Mira esa pinche wey. Yo voy a matar el"
Meaning "Look at thatfucking bitch/fag. I'm going to kill him"
3)Saying "Ore le wey!" figuritively meaning "Pray dude!"
Mira esa pinche wey alla. No me gusta esa wey.
No Mames wey!
Yo se que tu quieres chuparme las kenepas wey!
Also: wey we güey buey
A shortened derogatory noun or adjective used by Mexicans. As an adjective, it signifies mocking ignorance. It comes from "Buey" (meaning an ox with its genitalia cut off). The meaning is strong enough, the use of this word may be offensive unless you use it to playfully name a close friend.
Someone being "such a wey" would be "such an ignorant".
Someone being named "wey" by a friend is playfully being called an "ox with its genitalia cut off".
My LA experience saw a conversion of the word "Buey", meaning Ox, to Wey, meaning asshole when you wanted it to, or "dude" when you wanted it to. I would like to hear more about the use of buey as an insult.
