Idiom abuse is a slap in the face of grammar

In a rather amusing blog post, Sanya "Tweety" Weathers, MMO community guru and Director of Community at GamerDNA, reflects on the etymology of the phrase "a slap in the face" (as in, "The devs are nerfing Warlocks? This is such a slap in the face!"). Sanya seems to be of the belief that a slap to the face is more of a wake up call, with a potential curative element from temporary psychosis, which would seem to indicate that the phrase is being used improperly in this context.

For our part, we always wondered if people really felt like class nerfs or design changes were so insulting as to be compared with a physical blow to the face or if the phrase has merely slipped into the realm of meaningless idiom, joining "melting faces" and "massive damage" at the nexus of gamer parlance. Our suspicion is that people are just overly dramatic when confronted by change in an online environment, but you never know, some people take their games very seriously.
