boomerang children 

Children who move out of their family's house, purportedly to get jobs and/or start their own lives, but who return shortly thereafter to live with their parents again.

As the cost of living increases and jobs become harder to find, more and more parents find that instead of having an empty nest, they have boomerang children living with them.

Boomerang 

A guy or a girl that you slept or sleep with, and ignore him or her after you have sex, only to have them comeback for more without you making any effort. Kinda like a boomerang, you throw it away, but it always comes back to you.

O her?....Shes just a boomerang

Sin boomerang 

A sin boomerang is a woman of the attractive variety that is able to be recruited to acquire various objects of the self-destructive variety (such as drinks or cigarettes) from horny men typically in an environment in which imbibing is occurring. Upon acquiring the desired item, she then returns to her friend/friends to ration out the spoils.

"Dude, that party would have sucked without a sin boomerang. Those guys were being mad stingy with the Bacardi."

"Don't give that chick any cigarettes, she's definitely a sin boomerang."
