When an anarcho-capitalist suddenly converts to a far-left ideology, often anarcho-communism.
Anarcho-Capitalist; "Hey dude, will you join our capitalist discord server?"
Anarcho-Communist; "Sorry man, but I don't like capitalism anymore, I might go and pull a badmouse"
Anarcho-Capitalist; "TRAITOR REEEEEEEEEEEEEEEE HELICOPTER RIDE REEEEEEEEEEEEEEEEEE"
The adjective "Ballmouse" originated in Hull University halls of accomodation. During a LAN gaming session, a particular player would often be disadvantaged in the game by their use of a wireless ball mouse - (as opposed to a corded optical mouse)
During a game of Counter-Strike for example, a player may screw up their aim, miss, and get a pummeling from another player. One of the other players then yells "BALLMOUSE!" very loudly within earshot of the player that messed up - and raucous laughter ensues.
The word has since evolved such that it may be called out a someone being self-detrimentally stupid or proving their idiocy to themselves through their ill thought out actions.
n. software that is no longer sold or supported by the original publisher / developer, often found as free downloads on the internet because it cannot be obtained elsewhere. Not legal, but often seen as morally acceptable because the company that made it is no longer selling the title, nor releasing it as freeware, therefore abandonware is "keeping the gamealive", so to speak.
Doom II is not abandonware because idstill sells it, while The Incredible Machine is not sold, therefore is abandonware.
