One way to hold this use: a long word about a person is chopped in half and given a small -y ending. English does that to make words casual — but done to a person, the shrinking is the insult. What is left is a label thrown at someone, not a description of them.
A clipping of transgender (and, for the cross-dressing use, transvestite) with -y added.
由 transgender 砍短加 -y 而來；指變裝者的用法則對應 transvestite。

A different picture, and a different word that only looks the same. English long trans- words in workshops and living rooms and sticks -y on the end. Several separate machines happen to come out of that habit spelled tranny, so here the shared thing is the habit, not the meaning.
Separate clippings: transistor (radio) + -y, and transmission + -y.
兩條各自獨立的縮寫：transistor（radio）加 -y，以及 transmission 加 -y。
