when staying at someone's house, usually in the event of a one night stand. Neatly folding the clothes and leaving them near an exit allows the person to swoop-and-go
their clothes in the event of a rushed or forced exit.
I went home with a guy I met at the bar. When we got to his place, I folded my clothes as I took them off and left them near the door. When I woke up to discover he was really gross, I was able to swoop-and-go
my clothes for a hurried exit with out having to say good bye.
