Scratchitti is a form of graffiti
that's made by etch
ing and carving your tag
on an object instead of using tools like marker
ink or spray paint
Most commonly this is seen on the glass on subway
windows and school
Popularity for scratchitti has risen over the past decade as more cleaning agents were developed that eased the cleanup of traditional graffiti. Scratchitti permanently damages the surface thus giving it a longer lifespan. It's much cheaper to paint over a wall with graffitti than it is to replace an entire window covered in scratchitti.
