Usually a latina girl, but could be any nationality, is a female who thinks she's the shit and dresses like a hoochie mama all the time, even if she's just going to the store. For example, showing up at community college dressed like she's at a fucking club. And strutting her shit around to make sure the guys are looking, because her egotistical personality needs the attention.
Cha chas tend to wear open-toed shoes, flip-flops, and chancletas.
"I'm not going anywhere with you dressed like that! You look like a cha cha."

"Look at that cha cha over there. That fatty shouldn't be wearing a tank-top!"

it is slang referring to a current condition or situation that exists, usually pleasant.
We used to say, "Hey, don't mess up the cha-cha dude".

In this case the person did something to upset the applecart or cha-cha of someone else.

I have also heard, Go along with the cha-cha. Here it is like the word "program" as in go along with the program, or cha- cha.
