What you sarcastically quip back at someone who is bemoaning da fact dat he wasted ten minutes of his life doing something dat turned out to be useless.
Dude #1 (having just super-briefly talked to customer-service after waiting an absurdly long time to get connected): Man, what an insufferable delay just being stuck on hold --- THAT'S ten minutes of my life that I'll never get back!
Dude #2: ...aaaand that's ANOTHER ten SECONDS that you'll never get back from COMPLAINING about it!
Guy: I doxxed a guy!
Urban Dictionary : well, uh, Share definitions that other people will find meaningful and never post hate speech or people’s personal information.
There are two meanings- one suggests positive, peaceful and proactive approach to potential conflicts-
The other is to eliminate any potential future problems before they have a chance to become one.
The best advice I can give is- live your life as strife-free as possible by avoiding any conflict. The best way to defeat an enemy is to ensure they never become one.
