A form of scene anorexia. Skrillerexics see their scene stereotype as pale, skinny, size-zero-jean-wearing kids, and attempt to fit into this by becoming anorexic, bulimic, or a combination of both.
The term comes from Sonny Moore, whose myspace url is skrillex (also tattooed on the inside of his lower lip). Sonny is bulimic and/or anorexic (see "World War Me" or "Waltz More" on "Heroine" if you don't believe it).
"Maybe I should go skrillerexic. Everyone kept giving me these awful looks at the Haste the Day show last night."
