Trans-Exclusionary Radical Feminist. That group of feminists that claims that trans women aren't really women, as biological determinism is only a fallacy when it used against them, not when they use it against others.
Isn't it mindboggling that the Royal College of Psychiatrists would invite a TERF like Julie Bindel to come talk at a study day on transgenderism and transsexuality? That's like inviting Fred Phelps to come deliver the keynote at a gay pride.

Stands originally for “Trans Exclusionary Radical Feminist” but sometimes more widely used to anyone who is trans exclusionary (some people say it’s modern meaning stands for “Trans Exclusionary Raving Fools”

Simply put, a person who uses feminism to try and separate ‘real women’ from trans women, and backing it up with ideals of feminism. Some points of view call this “using feminism to be transphobic” while others say it’s “pointing out how roles/ideas/gender/statistics (how male sexual offenders are much higher than a females) are still applicable to a trans women”

It’s a bit hard to make a stance on, because on one hand, I think trans women are real women, and they should be fully integrated into the gender of women. On the other hand, I guess I could see how some people would be cautious with trans women, worried that they may act/think like a male. And then for both hands there’s a negative point of view too. It’s an odd word because you can use the ideology behind it in arguably favorable and distasteful way in everyone’s perspective.

Anyways, the word may also be considered a slur, but I haven’t seen any movement against the word or any site take action against the usage of the word.
person 1: trans women aren’t women, they’ll never be a female, always just as bad as the rest of men
person 2: get a load of this terf

friend 1: bro, don’t tell me you’re a terf
friend 2: I’m just nervous around trans women, what if they act like a guy? If we erase the social role of men and women with them, couldn’t that just be turned around to discredit the injustices women have faced?
friend 3: I get it, but if they are are trans women, I assure you they’ve fully transferred gender roles, the only difference is their biology. They will be just like the rest of us girls

stranger 1: this person just said they don’t think all trans women are the same as cisgender women, fucking pathetic terf
stranger 2: I don’t mean to be transphobic I support lgbtqia+ I’m just worried about what this means for women’s safety

From the acronym, Trans Exclusionary Radical Feminist, originally applied to anyone sympathetic to the materialist strand of feminism that seeks to counter women's inequality in the material division of reproductive labour and the objectification of women through sex-role stereotypes (aka "gender"). In defining women by the sub-set of males that women's boundaries exclude, the term centres male interests over women's and has been noted as a dehumanizing slur in UK case law.

In common usage, broadened to apply to any critic of gender-based policies, whether feminist or not.

Trans-Exlusionary Radical Feminist. Originally just named radical feminism. The basis of radical feminism is that gender is a social construct forced upon people at birth and are roles specifically designed to keep women subordinate to men (masculinity vs.feminity). Men, Trans activist, and liberal feminist use the term "TERF" because the principle of radical feminism cannot coexist with gender/trans ideology
Radical Feminists are inappropriately named TERFS to silence any female centered discussion

TERF in it's literal abbreviation means- "trans exclusionary radical feminist".

It's mostly used by Trans people and especially TRA's (Troons) - Trans right activists as a cop out and silencing tactic towards anyone that dares to question any part of gender identity politics/ideology. It's rarely used accurately and no research is carried out by the TRA to even distinguish whether the accused is even a feminist, never mind a, "radical feminist". It's so overused and thrown about that it's lost any real meaning. The majority of people simply view TERF as meaning- "anyone that questions or disagress with any factor of gender identity politics/idealism".

It officially fits the definition of a slur as it's consistently used in an aggressive and derogatory manner in order to slander and victimise anyone that doesn't fully comply with gender identity. TRA's and Troons are known for making violent and threatening statements against those they label TERF's. Evidence of such can be seen in mass by searching TERF is a slur. Link will show.

TRA'S smugly believe they're accomplishing some great feat by calling people this, but due to it being null and void, generally those accused don't really care or feel any effect from it. In fact, just like "Queer" and other previous slurs, it's in the process of being reclaimed and worn as a badge of honour due to the fact that the accused made it so that a TRA had to resort to a cop out instead of providing any logical or factual rebuttal.

Guy: "yeh...sorry but trans women don't have periods. It's the shedding of the uterus."

TRA: "fck you TERF!!!! Yes they do!!!"

Guy: "a what? I'm not a feminist...at all. I'm just stating a biological fact"

TRA: "yeh whatever TERF, and its not a fact at all, trans women can have periods"

Guy: "again, I'm not a feminist, and no they can't, a period requires a uterus, only females have uteruses, so how can they have a period?"

TRA: "I don't care TERF, and no that's not all that a period is, trans women get sore stomachs and diarrhoea"

Guy: "umm.. so do I when I eat the wrong thing, its still not a period. A period is the shedding of the uterus lining, not a sore stomach or the runs"

TRA: "trans women are women. TERF!!!"

Guy: "I...I'm talking about female bodily functions, trans women are still biologically male?"

TRA: "you fucking evil TERF!!! Show your face now!!!! Where do you work TERF??"
