Get the Night Ranger mug.
When a woman motorboats an unconscious man’s butt crack while swinging his limp penis in a “helicopter dick” circular motion like a propeller. If he then wakes up, extends his arms, and flies around the room while she keeps motorin’, that becomes a Sister Christian.
We went out to dinner in his Tesla. Then he took me back to his place in Tiburon, we had a bottle of Rombauer chard, and he passed out. Whatever. I gave him a Night Ranger and took an Uber back to Novato.
