It seems to me that as the concept of "appropriate attire" vanishes from the public sphere--pajamas in the supermarket? why not, dude?--and the evidence of excessive caloric intake is ever more visible, our language for describing shameless bodily displays is becoming correspondingly more inventive, elaborate, and body-part-specific. I am naturally thinking of cameltoe (a k a "the other cleavage"), a startlingly apt and vivid metaphor, especially considering that its users are unlikely to be Bedouins or zookeepers. Then there's muffin-top (a k a "belly roll"), which seems to have originated in an Australian sitcom, "Kath and Kim"; it was named Australia's word of the year for 2006 and is now almost as international as "OK."
New to me, but well known to the cool kids for some time now, is FUPA, which I first encountered earlier this week in Kersten's comment on a You Look Fab post. It's an acronym, which allows for some definitional flexibility. Acronym Finder defines it as "Fat Upper Pelvic Area," while the most popular definition on Urban Dictionary is "Fat Upper Pubic Area." Both interpretations suggest gender neutrality. However, the group singing "The FUPA Song" (watch the YouTube video) assigns an unequivocally feminine meaning to the "P" in FUPA. (Read the comments for some alternate glosses.)
If you're still wondering what on earth I'm talking about, you can check out the photos at FUPA Hunter, but don't say I didn't warn you. This is raw, in-your-FUPA documentation. This is muffin-top on steroids, inhuman growth hormones, and a side of fries.
