dormcest
n.— «Most dorms these days are coed, or segregated by floor (sometimes halves of floors) at worst.…People settle into a reasonably mature boundary-respect inside the first week or two. Floorcest and dormcest do happen, but if they get too active, they’re frowned upon.» —“Re: ASSD: Request Help with Story Search on Dorm Sex Party” by Adrian Mailenna Usenet: alt.sex.stories.d Mar. 15, 2005.
