Quite often
people's shapes, are compared to fruits, like pear, melon, or banana shaped.
The only shape that has no fruit connected to it is the hourglass shape.
Body parts like
breasts can be compared to shapes too:
Melons (full and round), pear shaped (half full, most
people have this), pointy (where the nipple sticks out), hangtits (hanging banana's), or flats (no tits)
