What is a troon?

Originally it's "tr00n" and this particular spelling was used in an effort to bypass the AI censors on Twitter who would suspend accounts critical of transgender ideology, via keyword triggers for trannies, and trans.

It kinda stuck.

[Apparatchik]

Poltroon refers to a spiritless coward or a mean-spirited wretch, often used to describe someone who is utterly cowardly. The term has its origins in Middle French and Italian, and it has been in use since at least the early 16th century.
