Generally used when quoting someone, especially (but certainly not limited to) in the context of an internet game forum. Hurf durf occurs when someone goes on a long-winded tangent about something that is universally insignificant but is present in the original poster's mind and is EXTREMELY important to that person. A declaration of hurf durf is generally directly followed by an ad hominem or general attack on the idea which was proposed.
Most often occurrences of hurf durf are unreasonable demands to alter a law or game mechanic so it will serve the needs of a very specific group, leaving all others effected at a disadvantage.
In real life, Calls for laws to consider obesity a physical handicap would be considered hurf durf because obesity is a self-inflicted condition and penalizing the rest of the population with higher taxes because fatty can't put down the donuts would be generally unreasonable.
In a gaming context, requests for a buff or nerf that would make one specific item or class unreasonably superior would be considered hurf durf, as it would destroy balance in the said game.
