an oblivious fool; a man with terrible fashion sense, bad manners, and/or terrible judgment, but is generally unaware of that he is making a fool of himself

Even though you recieved the best grade in the class you dont need to act so chachy. OR You are being a complete chachball.

A Chachi is a heterosexual male who could be charectorized as a metrosexual with a white-trash-won-the-lotto clothing style. They wear all the major designer labels but clash horribly as they mix styles at random. They also sport strange hairstyles and mullet remixes and tend to wear blush and lipgloss. They can be found singing along to hardcore rap, boybands, or dancing to techno tunes in the local clubs. Fortunatly this awful metro sub genre is for the time being found only in Europe and very prodomninatly in Switzerland. If you are ever in Zurich you will be sure to see several hanging out at the local McDonalds before clubbing.

Me: "Wow I think that kid wears more makeup than a 14 year old hooker. Or is that a 14 year old hooker?....hmm... nope it's a Chachi"
Or:
Nik: " Hey you wanna head to that new bar in town."
Christina: " Hell NO!! That place is totally Chachi"
