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
1.Man did you ever play Halo.....that game is so gacho
2.Dude!That guys new truck is freakin' gacho
3.Oh crap, those gacho beans gave me an upset stomach from h3LL.
Used in Spanglish (sometimes referred to as Pocho) this South Texas colloquial phrase describes a situation, person or group that is exceedingly difficult to deal with. Also, however not as often, the phrase can be used to describe something that looks cool or tough.
