Sin-Conscious

When someone frequently asks themselves whether or not they could use the sine rule or any sine-related formula to solve an unfamiliar sexy-looking geometry or trigonometry question.

When asked before a group of math educators at a church meeting if he sees himself as sin-conscious, David was tongue-tied, because he’s not sure if it’s a math or morality question: Could they be asking him if he easily succumbs to temptation when, say, seeing a scantily clad woman in public or on Facebook or on magazine covers?

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."
