An alternative name for having sex, especially when doors are closed and the shoes of the people having intercourse are left outside of their door. Inspired by an episode of Kimi ga Nozomu Eien (anime) where two of the main characters left their shoes outside of their apartment before having sex.
"Dude, their shoes were laying outside of their dorm, so I didn't open the door, even if I had to study with 'em. I'm not gonna walk in on a shoe scene!"
