A TERF is a Trans Exclusionary Radical Feminist.

J.K. Rowling is a huge ass fucking example as a TERF

Originally meant as a slur against individuals with gender critical beliefs, it has now been appropriated by those it targeted. Gender critical advocates -- those who believe only two genders exist and/or sex is determined at birth and cannot be changed - now typically use the word as a "badge of honor," including it as a self-descriptor in social media bios, etc.

The general public as a whole is beginning to redefine the term completely. Whereas it was originally as an acronym for "Trans Exclusionary Radical Feminist," many people now consider the acronym to stand for "Trans Exclusionary Rational Feminist" or "Trans Exclusionary Reasonable Factualist." These alternative acronyms reflect the growing scientific consensus that gender is binary and one sex cannot transitioned into the other sex.
She was attacked for her gender critical beliefs, but she defiantly declared, "This TERF won't relent. A woman is an adult human female."

Trans exclusionary reactionary fool. While most people say 'radical feminist', excluding trans women from feminist movements is not a feminist thing to do.
I used to admire her, but she outed herself as a bloody TERF.

When a woman reaches an older age in combination with a lack of self care. Due to the recent trend of looking out for possible transexuals, they found themselves kicked out of the woman's bathroom for resembling a man, regardless of being a biological adult human female. This cognitive dissonance leads the individual to spiral into a deep psychosis of constantly thinking about transgenders and what could be in their pants, in a brazen attempt to rid the world of the "evil" that they were accused of themselves. Unbenounced to them, their rhetoric is only encouraging others to judge manly biological woman, and blame it on biological males for looking better than them.
That's lady's a terf. She was born a woman and let herself go, to the point where she no longer looks like one.
