I remember seeing pictures of a trend in Japan a few years ago, where young and not-so-young women were wearing these really low-hip riding jeans. Their 'trick' was to wear thong undies so that the T-back of their underwear will show beneath the jeans.

Even without the jeans and no matter how nice your butt is, I don't think that the 'butt cleavage' trend should really catch on.

I personally do not like the thought of some stranger ogling my butt while I'm wearing really low-cut jeans -so the butt cleavage for me is definitely not hot, it's totally gross and not at all fashionable!!!
I'll keep those butt-cleavage showcasing antics in the bedroom if I were you -"exhibiting" it in public will just shock the hell outta your grandma.

What about you -do you think that butt cleavage is hot or disgusting?
