look up any word, like fuck boy:
Piss-stain graffiti is graffiti that is sprayed on someone else's property. It always lacks creativity and is sprayed for the purpose to look cool in front of your friends. It won't make you look cool, but it will make you an asshole.
Poser: Hey dude, check out what I tagged last night!

Normal kid: You fuck-up that's piss-stain graffiti!

*Poser gets beat by the normal kid*
