Most people look at the back of a book and read the blurb to get an idea of whether they want to read the whole thing.
The act of checking out a chick's booty
, or 'reading the blurb', is a very similar concept. Of course 'the blurb' isn't everything, but for some, it tells them all they need to know.
"Damn did you read the blurb on that chick
?! I would love to flick through her pages!"
"Have you read many books recently dude? Nah man, I've been reading the blurb a lot though, trying to find the right one for me you know"
