A person fighting against official/any gender assignments ("penis = male / vagina = female") and
structures that want to beat everyone into genderroles just for having a specific genital shape.
Also denying categories like "cis(sexual/gender)", "trans(sexual/gender)" and inter(sexual/gender)"
because they are the same way "genitalist" as saying a person with a vagina is automatically a female.
Usually an activist or influencer who is experiencing genitalism from time to time.
"Today I was on an antigenitalistic lecture. Didn´t know how much those people are fighting with gendercops a life long."
"You should not dare to ask my girlfriend if she´d be trans, inter or something, she is a strict antigenitalist and would put you into a very long and unpleasent debatte."
when you're holding up your phone and making faces at it, as though you are taking a selfie, but you're really taking a picture of the person across from you or the wall or anything else that seems interesting but you don't want to be caught dead taking a picture of.
This action is often made more convincing by wiggling the eyebrows or opening the mouth, to pretend you're trying to get a Snapchat filter to work.
FRIEND A: "Did you just take a stealthie of me?"
FRIEND B (turning phone around): "no I was just using snapchat's new filter, see?"
