USP

USP is a three lettered acronym for 'Ultra Sankt Pauli', a graffitti tag which is possibly related to the St. Pauli football club. The origins of the USP crew are unknown, most likely ex-secret agent ninjas with a penchant for explicit violence and an appetite for destruction. Other graffiti crews possibly have what is referred to as beef over disputed territories and tags being crossed out.

Possible toy(s).

Q3:Which writers lack artistic expression and skill with their quick tags?
