Is it normal that i clean my fingernails with toothpicks?

You could get a splinter!

its normal bro
but tooo normal

I use my other fingernails. Or a nail brush.

Sure. I use my pocket knife or my slanty tweezers, or whatever.

I used the needle of a compass (the drawing instrument) for that purpose while I was a schoolboy.

There are better ways but whatever makes you happy.

No you're a weirdo
