Look at that rack!, is an emotion or feeling of intense desire in the body mostly males have when they see a pair of huge honkers. The lust can take any form such as the lust for
knowledge, the lust for sex or the lust for boobies. It can take such mundane forms as the lust for food as distinct from the need for food women. Lust is a powerful psychological force producing intense wanting for an object (breasts, boobies, women, and SEX!), or circumstance fulfilling the emotion. Many so called religions separate the definition of passion and lust by further categorizing lust as type of passion for something that does not belong to oneself.
Why do men like or lust for breasts?Edit
When breasts are bare the man's brain becomes infatuated with the udders. He wants milk from that woman not that he can but he knows she's free for a milksome.
