Ironic slang term for a transfeminine person, modeled after "foid" and "chud." It is used jokingly in terminally-online spaces and falls under the foid and chud family. It's INTENTIONALLY used with incorrect grammar such as "an fud." Not a serious nor sociological term at all.
“I asked her pronouns and she replied ‘an fud."
"Bro this fud wants to crack me, I'm scared..."
“Fuds are literally God’s greatest gift to us mortals. Bow down.”
