First off cheap is in the eye of the beholder. For instance I was playing Team Fortress 2 and was accused of camping as a SNIPER in instances like those its not cheap its just playing the game using a tactic. If were staying with competitive games the only examples of cheap are glitches/exploits/hacks there may be a few examples of true overpoweredness (looking at you AWP) but mostly sore losers call cheap at any death.
Here's a story I know a guy who had a friend (lol sounds fake but trust me this is true) who was ranked on the top 100 halo 1 players in the world and one thing he would say is even pros can lose be it a bad day or a lucky shot. Classy.
