I meant more like "Hang a sock on the doorknob" for the roommate/buddy sort of kink code. You know, kind of like letting a bud know on the downlow that you met someone in Ibiza and hey, you had a good time. Because otherwise, everyone and their freaking grandmother knows you two are Grade A perma friendzoned? I've been to your place before. Yeah?
I hope that's clear now. Otherwise, I have zero probs cranking the flames up and burning down the conservatory.
