Quadruple Boob Syndrome (QBS) is a very common disorder among preteens and adolescence. It's when girls don't really know their bra size so they end up buying a super bad, super TIGHT bra that cuts their boobs in half horizontally. Then to make things worse they wear a skin tight shirt that clearly shows this. There are many cures for this disease. The most common is buying a bra your size.

The act of putting two women next to each other and motorboating between the innermost breasts while fondling the outermost breasts. It is called this because a jet boat is far superior to a motorboat and there are four breasts involved.
