Don’t bother arguing with people on social media because you are just tilting at these

I’m the footwear of cowboys, I’m useful on rainy days. I protect your feet from mud and dirt But if someone gives me to you, beware, It means you’re no longer welcome there. What am I?

I’m all around you, but not all you breathe. Without enough of me, life grows very brief.

A pirate taught me how to swear, Now every sailor gives me a glare, I can be your wingman, I'll lean on your shoulders like none can, Secrets are something I can't keep, And everything you tell me I repeat.

If you can do this with cash, I would love to hear your ways. If the same instructions apply to your lawn, I will just step aside. With teeth that scrape, I am a tool, or a phrase about big paydays.
