Noun; A numerical measurement of the extent to which a person is a twat. Similar to electrical wattage, the notable difference being that a higher twattage indicates a dimmer lightbulb rather than a brighter one.
A disaster of twat that reaches beyond the magnitude of a cuntaclysm. This word should be used in only the most extreme of cunt-riddled situations. A twatsaster often involves damage of personal property and can be accompanied by the need for rehabilitation.
I had to brave the mall so I could buy my girlfriend a purse and 6 bitches slammed into my new car, all while they were drinking their Starbucks, talking on their pink iPhones and fuckibg with their makeup. It was a fucking twatsaster!!
