This reminds me of "cheesing" in online games, where someone figures out some minor game imbalance that's cheap and easy to do and exploits it. No hacking or cheating, just playing the game as-it-is rather than as-it's-intended. Examples are camping in FPS shooter games, spamming hard-to-block moves in fighting games and Zergrush-like strategies in RTS games. People will say it's cheesy and a dishonorable way to win, but then again, you're winning--all completely within the rules and parameters set out by the game. The people crying "cheese" are playing a different, constrained and harder game, self-imposed out of some sense of purity or honor, and are upset that they're not winning.
