ladyrection
What happens to girls when they see hot guys in their underwear or completely naked, especially if they're doing something embarrassing. It makes them blush, giggle, or spend an hour in the shower.
My neighbor saw a guy walking to work in his underwear and fell over laughing.
I got ladyrection when I saw my crush and his friend doing something weird in the gym.
My best friend saw her crush and screamed like a mad person.
