Booger -is a slang term for the particles formed together in your nostrills. They stick together and /or sometimes harden because of the moisture in your nose.
Snot or Klinker - Slang term for mucos coming out of your nasal cavity.
(Note: These are not official definitions, and I am snot an expert)
If your nose is too dry you can just blow it and it will clear most of the particles (except those stuck to the walls of your nostrils). The problem you have may not be you, but environment. I had a similar problem because of where I worked. Lots of dust, dirt heavy machinery, kicking up more dust and crap. My only resolve was to take a warm shower after work, build up a little steam and then just blow my nose in the shower. This way you save paper and your nose. Hope this helps.
