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."

sin semilla

Literally "without seed." Used to describe high quality marijuana because it is normally void of seeds.

From "Smoke Two Joints" by Sublime:
"Toke a big spliff of some good sin semilla"

Sin Biscuits

Sin biscuits are when a cat makes biscuits (kneads) in an attempt to reproduce or rub one out. This is done with either another animal or an inanimate object like a stuffed toy.

Susan: Look how cute my cat is! He's kneading that toy so intensely!

Mark: Hate to break it to you, Susan, but them's sin biscuits.

Sin City

The brain child of artest/writer Frank Miller. Sin city takes a Film Noir city, Basin City, and puts comic book situations within it. Recently made into the most loyal comic book adaptation movie, Sin City is, perhaps, among the most revolutionary comic books to date.
