Taking a piece of thread you blame the exploits of your past on poor judgment. You tie this thread around your finger to remind you of all the exploits you accomplished in your day. Most of them weren’t actually on purpose, so you blame them on poor judgment and accident.
One of your exploits was when you got dressed in the dark and were wearing funny clothes and everyone thought that it was sexy (せき). The newspapers and fashion agencies couldn’t get enough of your sexy style.
