New words are a joy, none more so than words that describe perfectly something that’s been hard to describe previously. So, thanks to M@ and Sarah (non-existent online at present) I now present the following:
Gazebay (v)
The act of someone jumping in at the last moment of an Ebay auction with a slightly higher price, in order to secure your winning of the item being bidded on. So if a devious rotter gets that CD you had your eye on, and were destined to buy, by offering an extra 10p for it with less than a minute to go, you can say “I’ve been gazebayed!”. It’s like being gazumped on a house purchase.
