literal shit
for use when someone actualy shits when they get scared.
you scared the literal shit out of me!
literally shooting the shit
Shooting actual shit. That's right, as in pooping. Not conversing, talking, or otherwise socializing, but instead shooting actual shit. Don't say "literally" unless you mean it to be literal.
"She was on the toilet literally shooting the shit for hours. It was an unpleasant experience for all."
Literally full of shit
When your digestive system is backed up to the point where the majority of it is filled with partially-to-fully digested food.
God, I'm so constipated, I'm literally full of shit.
