EAT THE SHIT OUT OF IT
A fancy way to tell someone to go to hell and bring their whole family.
My mom told my brother, 'Eat the shit out of it, and don't come back until you're ready to die.'
I told my teacher, 'Eat the shit out of it, and I'll fail your class.'
My friend told his ex, 'Eat the shit out of it and never come back.'
