All body modification is just piercing the skin.

Piercings, obviously. Tattoos, there's also a needle that pierces through the skin. Scarification, implants, you're cutting the skin which is a different kind of piercing. Tongue splitting as well. Coin slots are just a biiiig piercing procedure.
All body artists are actually specialised piercers
@iro_miya @[email protected] well actually, the best hrt is injections (or implants) and that is also a kind of specialized piercing
@iro_miya heart surgery is also just a piercing when you think about it /s
