1) A pride symbol in the gay and lesbian community.
2) A kick-ass Weezer song.
1) He/She is gay. Check the pink tri...
2) "I'm dumped she's a lesbian, I thought I had found the one.. We were good as married in my mind, but married in my minds no good. Pink triangle on her sleve, lets me know the truth, lets me know the truth."

Rejection (of a male) by a girl who's a stealth-lesbian. Derived from the Weezer song.
"So how'd it go with that girl at the Dresden Dolls concert last night?"
"Shitty, man. We had fun, but I got totally pink triangled."

"I'm dumb, she's a lesbian. I thought I had found the one. I guess I got pink triangled."

When a guy falls for a female only to then find out she is lesbian. This is especially the case when the chemistry between the pair in question is seemingly quite strong.
Devon: Yeah so after she took me out to china town for lunch, studying in her room, and doing a yoga class together...she told me she was a lesbian.
Arthur: That's harsh man
Devon: I was totally pink triangled! I haven't felt this close to a girl in years!
