For me (I’m 46 so I think I’ve reached “get off my lawn” age), it’s short for “this [is the correct answer.]” So I’ve never had a problem with it and probably used it once or twice myself.

A couple summers ago at the pool I heard a teenage girl exclaim “poned!” after besting her friend at something they were playing. It took me a moment to realize she’d just said “pwned” since I’d never heard it said out loud before and in my mind I’ve always read it “owned.” Now that was a “get off my lawn moment!”
