Femboy

A femboy is a slang term for a young, usually but not limited to cisgender male who displays traditionally feminine characteristics such as clothing or mannerisms. While the term can be used as an insult, some in the LGBT community use the term positively to name forms of gender expression.

Term
The term femboy originated in the 1990s and was used as a derogatory term to describe cisgender boys or males who had femenine qualities or present themselves in a femenine way for non-sexual purposes.

The modern use of the word may be tracked to the use of the term "trap" or otokonoko on anime image boards such as 4chan in the mid-2000s.

Gender and sexuality
A femboy or trap is originally used as a term to refer to a boy/man who crossdresses. It is notable to say that a trans woman can refer to herself as a femboy and keep her transgender identity, but it is false to affirm all femboys are transgender or imply Trans man cannot be femboys due their biological sex while having a masculine gender.

Aesthetics
A femboy is different to a Cross-dressing thanks for their aesthetics. While a crossdresser uses common femenine clothes, a femboy is closer to the femenine emo, Goth subculture and kawaii subculture.
