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!!
Me: Hey you want to come over after the party? Bryan: Yeah sounds good. Andrea: Oh, hey Tatiana. Does your boyfriend know your out tonight? Me: Uhh... Bryan: *Gets up and walks away* Me: UGH! You goddamn twat swatter! I almost had him! I'm kicking your bony ass!
