Strangers don't tell strangers they have attractive jiggles because they risk getting slapped or responded to with the phrase "Geez - what a dork!" It's a bit too personal. I HAVE walked up to complete strangers and complimented their clothing, hair, tattoos - that sort of thing, but those are all artistic things they had control over.

Friends don't tell friends they have attractive jiggles because of the possibility one or the other might take it a bit too seriously. I've had close male friends for most of my life, and I can't recall any of them ever commenting on my physical attributes seriously. I feel like we're lapsing into a Seinfeld episode...

Jeans DO come in different sizes:
Juniors: Can't squish my legs into them - forget the rest.
Misses: Butt fits great, but the waist cuts off my circulation.
Womens: Can find a waist that's big enough, but there's enough room for my butt, a friend's butt, and a couple of ferrets per thigh.
