Nope, not swearwords. We're talking the verbs, nouns and adjectives that strike an irksome chord with every gamer. Companies with notorious histories, cultural watch-words, error messages shared by a generation. These are gaming's dirtiest words...

Fanboys
Gaming culture's trainspotters, commonly spotted engaging in nuclear-strength arguments on comment threads of aggregation sites or forums. Generally split into three camps: Sony soldiers, Xbox zealots or Nintendo nutters. Note: Level of console commitment is inversely proportionate to grammatical and vocabulary ability.

"Did Joey see the new Zelda?"
"No, Frank! He's a Sony fanboy, if you showed him that he'd be physically sick!"

Disc Read Error
Common PSone/PS2 error message euphemism loosely translated as "rub the disc a bit with your jumper, turn your console upside down, try again and pray really, really hard".

"Why's your console perched upside down on the cat at a 45 degree angle, Tom?"
"Disc Read Error"
