ladyrection
The crazy feeling girls get when they see hot guys in their underwear or completely naked, especially if they're doing something dirty. It makes them blush, laugh, or take an hour in the shower.
I saw my crush and his friend doing something weird and started laughing like a maniac.
My friend saw a guy doing push-ups in his underwear and screamed.
I got ladyrection when I saw my neighbor walking to work in his boxers.
