Sineni 

Not close to human, not far from retardation. An awkward stoplight that does the "truffle shuffle" to the tune of Happy Feet.

Dude this stoplight is being a complete Sineni right now.

Selective Sinning 

When someone who’s usually a Christian, only abides by some rules in the bible that they deem morally wrong. Like gays go to hell, but they still get drunk or watch porn.

Someone: Why is Barb getting a divorce does she know it’s against the Bible?

Me: Oh she’s just Selective Sinning.
