Screwing over a consumer by forcing him or her to purchase a large amount of games and/or accessories at the launch of a new console. Usable as a noun or verb.
"Gamestop's XBOX360 Ultimate Bundle costs $1200 but doesn't even include a second controller! What a bundlefuck!"
"Electronics Boutique really bundlefucked me when I bought a PSP - I only wanted Lumines but they also forced me to buy crap games."
Offensive, chiefly Brit. Contraction of bugger (sodomise), fuck (fornicate), and twat (cunt).
Used as a superlative in the rare case that two expletives will not suffice, to describe someone so utterly contemptible and stupid that the utterer has to search her mind for a sufficiently potent approbrium.
What?!! You sold your twelve year old sister to a Romanian sex ring mafioso for half a cabbage? You... You... BUGGERFUCKTWAT!!!!!!
