Someone who exhibits lame tactics in competitive sports video games, usually against a human opponent. This could include but is not limited to running the same play over and over, using clock tactics, or anything else that isn't in the spirit of friends sitting down to waste time playing video games.
Player: "Man you're milking the clock in a video game? That's fucking twatballing, man"
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!!
No bitches wanted me when I worked at Burger King, but this big time job waiting tables at Denny's has transformed me into the...da da da da...twatmaster. That's clit commander in layman's terms.
