The smallest possible unit of giving a fuck—an indivisible quantum of concern. Analogous to the Planck length in physics, it's the theoretical minimum amount of care one can give before it ceases to exist entirely.
“I don’t give a single Planck fuck what you think.”
“That’s a Planck fuck less than I gave yesterday.”
“Somewhere between zero and a Planck fuck is where my interest resides.”

Get the FUCK PLANK mug.Related Words
Sex where, usually the partner on top, is in a plank position. The bottom partner can be in any position underneath and any hole or area can be being penetrated: mouth, anus, vagina, breasts. The key is that this action also doubles as an intentional intensive core and ab workout for one or both partners.
Damn, my abs are looking ripped after all that plankfucking last night. I’m skipping my core workout at the gym today!
