Gay Panic Attack 

Definition accustomed to queer folks who love women but can be applied to all the LGBTQ+ community:
The moment when you see a beautiful woman and you just get overwhelmed by her beauty so instead of figuring out what to do next, your brain gets stuck into a loop of aggressively internally screaming WOMAN.

Friend: Why didn't you talk to her if you found her attractive.
Me: I couldn't, I was having a Gay Panic Attack.
