a and r
Rest and Relaxation is what you need after being yelled at by your mom, your boss, and your ex all at once. It's like a vacation for your brain.
I need R and R, or I'm gonna scream in the middle of the grocery store.
After that meeting, I had to take a full day of R and R. I slept through the entire weekend.
R and R is just a fancy way of saying 'I'm too tired to be mad anymore.'
