Gay; An invalid insult (that is a pretty shitty thing to do, and is homophobic tbh...) Or is a homosexual man. It could be generalized and just used to group up all of the LGBTQ+ people up! <3
Example (of what me, a trans person would say.)
me (aka august): ARE YOU GAY??
person: yeah why
me: ok cool
person: bye now
slay uwu (also gay people are very valid <333)
