It's two words, but what's been bugging me lately is "hands down" (even though I've probably been guilty of using it). As in "hands down, restaurant X has the best XX in WDW," when in fact you can tell that the writer has never even tried the XX at restaurant Y or Z.
This is especially prevalent in the numerous "best steaks" threads. If you haven't eaten at Shula's, Bull & Bear, STK, etc., how can you claim that another restaurant has "hands down" the best steaks?
By the way, I think "inedible" is a valid descriptor when used to describe seriously flawed food (bloody chicken, ammonia-scented fish, pizza with raw dough, etc.). Although rare, I have definitely been served inedible food at WDW and elsewhere.
