What do people mean when they say I have sandals?

People say you are a sandal, which means that since you are a sandal, anyone can wear it? If you can't wear it for a long time, you may be thrown away, so that means you are a very worthless person, unworthy of everyone's trust and unworthy of people's association. The reason why I give you association and don't give you play is the knowledge map, which uses you. It also shows that you are a straw sandal and a very dissolute woman. People give you associations just to use you.
