What are some "disgusting"/unsociable habits that you have, that others might find disgusting, but YOU love doing?

For instance: I love picking my nose, playing with it between my fingers, rolling it, cutting it with my nails, then flicking each bit. πŸ˜‚
I also love (most of the time) the smell of my own farts. πŸ˜‚
I like to run my fingers/nails over my skin and find pores that need unblocking and pick them out.
I also crack my joints a lot too, but this is due to pain, more than anything.

I'm curious as to whether you can be honest and what you will tell.
I will say, that all this.. I do in private, and I don't see anything wrong with it. πŸ˜ŠπŸ™„πŸ˜‰
