I can't f*cking stand tech buzzwords. Hearing people say crap like "paradigm shift" "sideloading" and "prosumer" fill me with a murderous rage. What buzzwords do you hate? Are you one of the annoying people that says them?
Oh, and "touch base." That's more of a straight office buzzword than a tech thing but, for the love of God, stop saying that. Seriously...stop.
