An umbrella term for individuals (usually on
tumblr) claiming identity with anything beside the standard
gay,
bi or transgendered sexual identities/orientations. Such extra labels are seemingly made up as a product of those considered to suffer from "Special Snowflake Syndrome" and are only used to garner attention.
Jimmy: Hey
Marcus! How'd your date go with
Linda last night?
Marcus: Utter shit. I tried complimenting her and told her she was the prettiest woman in the bar, she flips out and goes, "I'm not a woman, I'm a trigendered omnisexual who HAPPENS to be in a female body."
Jimmy: Fucking tumblrsexuals man...
