Greasing the Cross 

Basically a Christian masturbating (inspired by another masturbation phrase called 'Greasing the Monkey').

This is sometimes done to piss off extremist Christians who think that you'll rot in Hell for jacking off.

Regan from The Exorcist was greasing the cross before it was cool.
