I'll take that and raise you the over-use of 'simulation'.I hate the over-use of the word "verisimilitude" that RPGers are so prone to.
Because when gamers use 'simulation', it usually means something akin to 'an eclectic collection of details and/or processes which interest me, absent a logical framework placing them in context, describing how they fit together, or lacking an explicit statement of what's being simulated' (other than, "umm, reality, and stuff").
My favorite current examples can be found in any online gaming discussion involving simulation, hit points and healing surges.
Other than that, I try not to hate on the players or the game (and the DM/GM)!
