The act of fussing over the physical appearance of your significant other, akin to scenes of monkeys or other simians doing the same on animal documentaries. Includes squeezing pimples/blackheads, manicuring, pedicuring and plucking funny and/or white hair. Provides presumed psychic gratification to the groomer and laid back enjoyment to the groomee.
"What're you doing today?" "Nothing much. Monkey-grooming each other."
