10. CIS and TERF

The most familiar acronym is TERF. From Wikipedia:

TERF is an acronym for Trans-Exclusionary Radical Feminist. First recorded in 2008, the term originally applied to the minority of feminists espousing sentiments that other feminists considered transphobic, such as the rejection of the assertion that trans women are women, the exclusion of trans women from women's spaces, and opposition to transgender rights legislation. The meaning has since expanded to refer more broadly to people with trans-exclusionary views who may have no involvement with radical feminism.

And as for CIS:

Cisgender (sometimes cissexual, or shortened to CIS) describes a person whose gender identity is the same as their sex assigned at birth. The word cisgender is the antonym of transgender. The prefix cis- is not an acronym or abbreviation of another word; it is derived from Latin meaning "on this side of."
