verb: Screwed up, botched, ruined. Something is said to be "lindened" when a situation is made worse by an action that was intended to make things better.
This word originated in the Second Life community in response to the chronic troubles following Second Life upgrades.
My brakes were squeaking a bit so I got them worked on - now they are completely lindened - it won't stop at all.
The process of taking something, and in an effort to improve it, making it worse.
Particularly as applied to softwear programs, wherein updates generally result in more bugs than they fix, or more old features broken than new ones introduced.
"He told me he was going to fix my car, but now it's all Lindened and won't even start."
