Means "trẻ trâu", a
slang in Vietnam, used to describe different types of
people that are usually toxic, edgy, stupid,... blahblah.
The word "trẻ" (Subject) does not mean "young" (Adj), It means "
kid" and "trâu" means "buffalo". It can be easily understood as a stupid heady
kid.
This word does not have an exact meaning now. No one knows where did it come from.
Bonus: You can meet these lil dudes in Vietnam's League server.
(Usually a Yasuo player, playing Yasuo does not make you a young buffalo, but every young buffalo likes to play Yasuo)
*In a
normal Vietnam's League match...
Yasuo: "My job here is done." (0/11/3)
Lux: "But you did nothing" (4/5/3)
*Yasuo has disconnected from the
game
Lux: "What a
f**cking young buffalo!"
