Damn, this annoys me.
In a review in Slate of the movie Wolverine, Dana Stevens smirks as follows: "The first time Jackman appeared shirtless, about 15 minutes into the movie, his absurdly pneumatic chest garnered one of the few laughs at the screening that I attended."
Pneumatic: "Having a well-proportioned feminine figure; especially: having a full bust."
That's the first part of the standard sneer at muscles - implying that they're somehow feminine, not really masculine at all.
The second part is the implication that a muscular male physique is inherently laughable and contemptible. Among a certain subset of the American population, this is a commonplace. For those people, the presence muscles is assumed to prove the absence of brains.
Jackman's developed chest is not absurd. First, it fits with the cartoon character he's playing. Second, to those of us who lift weights, it denotes the hours of hard work the actor underwent and his admirable self-discipline. What's absurd is Dana Stevens and her ilk. Perhaps she needs to spend a few hours in the gym.
