Boob chart 

A chart showing pictures or illustrations of a wide variety of breasts, varrying in size and shape, or even nipple size. Can be used to sort females into groups, as a party icebreaker (provided persons at party can take a good joke), as a referance for drawing or painting, or to compare the wide variety of breasts that there are. Usually created and used for comedic purposes.

Guy1: Look at all the babes at this party!
Guy2: Yeah, man! Gotta pull up the boob chart on Google images to sort these girls out!
Guy3: Nah, we should make one of our own using pics of 'em!
Girl: You guys are such pervs!
