Demented Foal Fountain (DFF)

When one masturbates sitting on the dunny and when approaching the vinegar stroke, stands up and staggers around like a new born horse shooting spooge all over the room, or public cubical you’re in,

A friend in the group who, while not necessarily being gay or any other LGBT+ subtype (although commonly a bisexual man) behaved in a way similar to the stereotypical idea of a gay friend. Most often referring to a male in a group of one or more female friends, and act as fashion consultant, chick flick movie buddy, late night emotional support, and most other stereotypical gay character traits commonly associated with homosexual men/heterosexual female friendships.

Similar to Designated Gay Best Friend or DGBF, but less specific to include any friend who fits gay stereotypes, regardless of their sexual orientation.
A lot of people ask me if he’s my boyfriend, but he’s my bestie, and he’s friends with all of my friends, so he’s the Designated Fruity Friend (DFF), and he’s just one of the girls!
