I bite my toenails.
I bite my toenails and save them in a mason jar.

Once the jar gets somewhat full I take a few out to chew, or I just rummage my fingers through it.
Once it is completely full I blend them into a powder and put the powder into a smaller jar and start filling the large one again. I lick my finger and dip it in the toenail dust and eat it like a dip stick.

I've taken some of the coarser powder and mixed it with shower gel for the abrasive properties, but once it's been sitting for a while they lose their roughness. I once mixed fine powder with toothpaste to see if it would act as a sort of fine sandpaper, it was too messy to try more than once and frankly, I thought it was a bit too weird.

You think that just because I masturbate to furry porn I'm a furry? Think again, maggot. The furry fandom is a breeding ground for the most advanced autism this planet has ever seen. Every day, thousands are consumed by a tidal wave of OwO and cancerous roleplaying, and the foundations of our society slowly weaken under the constant onslaught of weapons-grade cringe. Our founding fathers recoil in disgust as people dress up as animals and buy giant dildos on the Internet, ♥♥♥♥♥♥♥ each other in sweaty drunken homosexual orgies and traumatizing children in droves. Every second we draw closer to Furry Armageddon, and you sit there saying stupid ♥♥♥♥ on the Internet. To compare someone to a furry is the most heinous insult imaginable. When your door gets broken down by a rainbow wolf/deer hybrid and you get yiffed into oblivion, then we'll see who's laughing. This is a real threat and it must be treated with extreme solemnity.
