BOGO

My current nomination for "Irritating Coined Word of the Year" is BOGO.

Usage: On signs outside businesses we see "Widgets! BOGO Free!" It stands for "Buy One, Get One." It's been around long enough that we now see signs that just say, "Lipstick BOGO."

I never really did understand why they can't price that as 50% off, but it guess they do it to move old inventory. I mainly see BOGO on signs outside drugstores that are trying to unload cheap cosmetics.
