Seated at your desk during freetime, your friend comes over to your desk.

"Never thought you would get down with a girl on a school night."

He whispers with some amazement. Your friend assumed it was a girl, due to your personality(in public). But it was actually scaramouche, innocently sitting next to the window. He too had some marks and hickeys. Scaramouche catches a glance of you and winks playfully.
