As A Matter Of Fact, I had to google that because I’ve never seen anyone use that abbreviation.

It looks like it's in a binary format and is printing control characters because it isn't a format intended to be viewed/edited. You could try opening it in a hex editor and see if you can make any sense from that.

You can put whatever you wish inside of YAS-BDSM as long as everyone is having a good time.

Feel free to use it (or get used by it).
