It certainly lives up to that billing. Simply put, sniping is the act of placing a winning bid in the final seconds of an auction. Needless to say, snipers are not well-liked by other bidders.
Sellers tend to hold the opposite viewpoint.
I put Dennis Prince's sniping tips to the test at the end of a music CD auction, but I didn't win. But that was okay, because the auction price had risen above the amount I was willing to pay. I've done it, and you probably will too. For example, you'll be interested to know that there is a best time of the week to start your auction. And if you're a serious year 'round eBay auctioneer, you'll find the advice on prime selling seasons to be worth the price of the book.
