Read the girls' runes

Banti grins, peering down at a particularly busty girl who's crouched in the corner of the gymnasium. "Ooh! That girl secretly masturbates to dwarf bondage porn! That's hilarious!"

"Wait, you mean anyone looking at her runes immediately knows what kind of porn she likes?"

"Only if it's super embarrassing. Which it is! And the skinny girl down there has a huge crush on the captain of the basketball team, who's over there looking at her right now."

"What about her?"

"Still sleeps with a teddy bear."

"Her?"

"Cheats on math tests."

"Her?"

"Acts tough, but she's really scared of mice."

"Her?"

"Really, really sensitive nipples."

"Her?"

"Keeps a big pink dildo called Mr. Happy in a box under her bed."

"Interesting," you say, as the girls mill about and squeal and try to hide their naked secrets from the admiring public. Without much success, of course. "There's more fun we could have with them. Maybe we could tie them up or something."

"Sure," suggests Banti. "Or maybe we could check out the girls' dormitory. Might be someone else to prank there. I have to say, this is really fun."
