My Current Most Loathed Marketing Terms

"Share of Wallet" - what the hell does that mean? How much people spend at a given business? OK - so maybe it's supposed to be angled towards some sort of discretionary idea where people consciously/unconsciously dedicate funds that they have available to certain businesses... But really, this is bullshit.

"Webinar" - ooh, aren't I clever? I took the word "web" and merged it with the word "seminar" to refer to some sort of online video-y chit-chatty sort of thing. A more ungainly portmanteau I can barely imagine. May it fall into disuse again as soon as possible.
