gacho 11 up, 1 down

spanish slang
is the opposite of "chido", which means cool.
so "gacho" would mean 'not cool' or 'stupid'
but not so much the word "stupid" but think of it as the opposite of cool..whatever word that may be

que gacho, el chico que cree que es chido.

From the word GABACHO derives the slang term "GACHO" used by LA RAZA today, and is definitive of "wrongful-doings and/or bad-traits."

For Example:

A man who lives off the work of the woman ~ es GACHO de la mujer
~ He's a lazy sob living off his wife’s labor

A person that ain't worth a dime ~ Vale pa' puro GACHO ~
~ He's a real no good mofo'

A person who acts with contempt and disrespect - Que GACHO es el ~
~ He is a focked up dude

A bad deal ~ Que GACHO fue el trato ~ That was a focked up deal

A wrong treatment ~ Que GACHO se comporto ~
~ He acted all wrong

and of course the most commonly heard QUE GACHO ~ THAT'S WRONG
