Bosscat, the brand, is a maker of snow sleds. It isn't a far fetch to jump to ATV and other rec vehicles. It is in my opinion that people take screen names that have a personal meaning and connection to them.
I kept the quote in question, but I'm not sure if I can post that here. So I won't.
If you do a little sleuthing on this poster (Bosscat2), it's pretty easy to come up with a local that uses that name.
