Originally used in Ireland to describe a Catholic making a public display of religiosity simply for show.
Nowadays it refers to those who put on a big act to impress people, hypocritically. They creep around pumping hands and grinning like goons, oozing compliments and uttering clichés, all the while dying for a chance to stab you in the back. If you work with one you'll see people getting fired in their wake, and don't be surprised if you're next.
That Creeping Jesus charmed information out of me and then told the boss everything I said, to get me sacked, and he did the same to ten others.

It's someone who's a fawning person. But it's a bit rough, since when is Jesus associated with creepiness? Sure, he hung out with lepers - but that's not creepy. Social suicide maybe...

A catch all term for being "under the weather" with a cold, flu, hangover, et cetera.
