Usually an outlet of some retards/sickos for their miserable lives. They "re-enact" the crimes and stupid things that can be done in the game in real life. Once caught they say they were "inspired" and "influenced" by playing GTA but that's merely their lowly excuse for the lose screws in their head.
" WTF! damn sicko, he's probably playin gta up all night and thinks he'll get an Oscar's for doing that."
