eBay sniper
That sneaky bastard who used clever tricks to win the eBay auction you thought was yours and left you high and dry.
I was winning, and this sniper used some secret trick to get my item and I was left with nothing but sadness.
I had the highest bid, and some sniper sniped me and I had to buy it from them for double the price.
I was about to win, and this sniper used a bidding strategy so good it made me feel like a loser.
