In rock climbing we use “Gumby” no clue why.
EDIT: I’d like to clarify I agree about the gatekeeping this reinforces and this really doesn’t get used often, and if anything it sees more use among friends for silly reasons, like missing a Velcro on a shoe or something. Like I said I don’t know the origin because I don’t really engage with the “joke” that much.
I read that as “guy liner” at first.
