look up any word, like sweetest day:
 
1.
A name used by Australian Public Transport to shame those who graffiti on buses, trains and ferries.
"Don't be a graffidiot because cleaning up your mess is costing the rest of us more money"

Person 1: Your just a graffidiot
person 2: " WTFFFFF?????
Person 1: you know, the person every bus and train talks about on those stickers on the windows.
