A species of creature from the game "Borderlands" native to much of the Planet Pandora. These nasty bastards will attempt to consume just about anything with a pulse and many things that don't and therefore often consume the items of the unlucky tossers who got attacked. After doing so the Skag, unable to digest the items, will vomit them back up in characteristic "Skag Piles" often of which are smashed open to unveil the rather foul smelling goodies inside. Skags are rather odd creatures in and of the fact that their skull structure allows their face to slit into four separate parts to consume pray often much larger than themselves. In so doing they will often screech and roar in such a manner as to expose the soft and vulnerable fleshy inner parts of their head for easy bullet penetration, this often results in the death of any creature caught within a fight. Skags also seem to be able to consume the native "Element" of the environment they grow in and thus can begin to develop elemental powers resulting in abilities such as breathing fire or spitting globs of corrosive acid at enemies. One should note also that as skags age they tend to toughen and develop much thicker armor, the worst of these being Alpha Skags which have thick frontal armor and are less likely to roar and screech, making them formidable opponents in combat, the only real way to easy exterminate them and by in large any skag is through use of corrosive agents.

Tracksuit wearing teenagers with greasy straightened hair, too much foundation and hardly any eye make-up. The girls have choppy hair dyed crappy colours that make you think of underage prostitutes and the guys have badger dye jobs and mullets or just annoying spiky, gelled creations. They're obsessed with Rihanna, Chris Brown, Pussycat Dolls and all forms of bad/dance music. They're usually incredibly racist/facist/conformist and the discriminate against people who are in any way different. They smoke, drink, 'finger' eachother at 11. They represent 70% of Irish teenagers.
