Ex: Result of excessive sweating with hairy gooch.
"The hair on my ass is causing an SBH every time i walk."
"Dude every time i look in the mirror and pull my butt cheeks apart and look at my hairy gooch i see sweat dripping down from my SBH"
this describes girls (or guys) that seem really shy, sweet, and innocent, but in reality, they are the horniest people of all.
Boy 2: Oh, I know her. She's quiet, but she's an sbh, no doubt.
