"Chaya" comes from a gypsi slang. In Germany explicit in Frankfurt/Main "Chaya" is another word for 'hot girl', bitch, etc... It is only used for women. Men are called "chab" or "chabo" instead, but this word can have different meanings, so search for the definition.

Chaya is meant to be a hot girl and thus often adopted by young girls referring to themselves.

Unfortunately it is an orthographic mistake, hence the word correctly spells Tschaia or Tschaie, which originates from a whole set of 'moving languages' (Read gypsiy slang et al) and means plainly a girl.

Hence those languages are mostly spoken languages, it is usually hard to define the correct orthography, yet the transformation into chaya might be related to spanish (that certain latin(a/o) touch) or just shows the typical social lower class educational level.

chaya’s are girls who are amazing at heart. they’re hilarious and usually have dirty blonde hair. she loves her friends more than anything, and her family is very important to her. when you get to know her, she opens up to you and can easily tell you her whole life story while you sit there and listen, but afterwards she’ll ask you questions about yourself and make sure you’re doing okay as well. she makes the people she’s surrounded with happy, and she loves to do so.

A dumbass bitch who genuinely cares deeply about friends and family, but will hardly ever expose the fact that she has emotions. Generally gives off don’t-give-a-fuck vibes, but she does; slightly. She can also make you laugh for hours, therefore you should be friends with her if possible.

In Germany, especially in the area around Frankfurt am Main, Chaya used to described mostly brown woman of colour. It was often used by men to insult young woman of middle eastern background who wouldn't fit into the expectation of a good Muslim girl because of the way they act and look. Chaya were often woman with long black or brown hair, big earrings, heavy make up who came from a working class background.

Today chaya is often used as a self describing and empowering term by woman of colour in Germany. The black German musician Nura published a song named chaya. Because of its mysoginist, clasist and racist background the term shouldn't be claimed by anyone especially not by white woman from upper class.
