It's a D&D
term where you tweak a skill of your character to the point of detriments in another skills, and the Dungeon Master
specifically tailors the campaign to take advantage of that detriment, fully negating any point of pimping
out the skill you were focused on. Thus, your character is skillfucked.

I'm sorry Brian, I guess you shouldn't have poured all your skill points in to bargain, since there are no merchants in this campaign. You my friend have been officially skillfucked.
