Tranny
“Tranny” was originally a term used by transgender people to refer to themselves.
However, over time it started to be used differently - by people who did not consider themselves transgender, to refer to transgender people pejoratively.
As a result, it is now normally considered a slur and to be offensive, but some people who adopted the “tranny” identity in the past still use it. Others have also attempted to reappropriate the term by using it to describe themselves positively.
It is strongly recommended that you do not use “tranny” to describe other people unless you are absolutely sure they are happy for you to do so, and that other people around you will not be upset by it
