A guydyke is a man who, whether intentionally or unintentionally, attracted to lesbian women. A guydyke often pursues relationships with women only to find out that those women are not attracted to his sex. Some guydykes feel like they live a cursed existence of being attracted to a type of woman they can't have.

n. The birth name of somebody who has changed their name. Most commonly attributed to trans people, but can be attributed to any person who has changed their name. (sometimes written as two words: dead name)

v. 1. To call somebody by their deadname.
v. 2. To out somebody's deadname to the public.

The name given to a guy that likes/wants to have relationships with lesbians

A cisgender, heterosexual man who fetishises lesbians. The term "guydyke" is a self proclaimed label, and is an offensive use of the word "dyke" as they have no right whatsoever to reclaim the once-slur, since they are heterosexual. They also seem to enjoy using the word "queer", which is also a slur they have no right to reclaim.

Guydykes are incredibly homophobic and transphobic, as they see lesbians as nothing more than an object to fetishize, they compare themselves to lesbian trans women which spreads false information, and they try to get themselves into LGBT spaces and call themselves "queer" for their fetish, which is dangerous when accepted as there are a large portion of guydykes who aim to sexually abuse and even attempt to rape lesbians.

The male version of guydykes are girlfags.

There is an abundance of both girlfags and guydykes patrolling the voting area of Urban Dictionary to avoid definitions like this one being published instead of their sugarcoated, bullshit-filled definitions that are already in place.

A man, often but not always gay, who favors the stereotypically lesbian lifestyle, i.e., Birkenstocks, sandals, long scruffy hair, recycling, vegetarian pot-lucks, child-raising, etc. as oppossed to circuit parties, gym memberships, promiscuity, and fashion etc.
