catasser
n.— «There’s a term for people who involve themselves in virtual worlds at the expense of the real: catasser. It was coined by a fellow who let his cat suffer an unchanged litter box rather than pause his online gaming. His apartment took on the unpleasant odor of “cat ass” and the term took off.» —“In Search Of Lost Disposable Time” by Dave Elfving Machine Chicago Dec. 19, 2006. (source: Double-Tongued Dictionary)
How about a Computer + Fatass = CatAss?
