"Dude, I got totally GM'd at the hardware store!"

"What happened, bro?"

"They sold me this brand new high-quality precision screwdriver set; they said it was from an all-American company, but then I read at the back of the box that it was a 'certified pre-owned' kit and that it had been manufactured in fucking Mexico, can you believe that!"

"Man, that's GM! Did it come with a warranty at least? Maybe you can trade-it in for another kit or get your money back?"

"I don't know man, I feel I got totally GM'd."

"True that, bro."

Glamour muscles. Muscles that you work out that are only for looks - not for core strength.
From the show "it's always Sunny in Philadelphia" this is what Dennis called Mac's muscles - GM - Glamour Muscles - god dammit!

Dennis: Well, how the hell are you planning on getting in there, Mac?

Mac: Uh... you put me on the spot. First thing that comes to my head, scaling the façade. All right, I know I soured on that earlier, but I believe that is my mind telling me that I have it in me.

Dennis: Okay, I hate to tell you this, bro, but you do not have the core strength to scale the façade of Citizens Bank. You just don't.

Mac: What? I work out all the time!

Dennis: Yeah, but you only work out your glamour muscles, and you know it.

Mac: I work out my core.

Dennis: No, you do not work your core. You're totally arm-heavy. You're all bis and tris and everything else is just fat and-and ribs.

Mac: Bro, I can do way more push-ups than you, and that's like 16 different muscle groups, I think.

Dennis: That is beyond retarded, what you’re saying right now. edit
