Perhaps,「hole with dirt and turtle shell.」The「turtle」element has no「head」so it may be that an inverted, empty shell is used here as a container for the food (so that turtle meat and intestines are not the supper, this time), placed upon dirt that was layered over hot coals and meaning a COOK STOVE. Note that placing the turtle shell directly on burning coals will soon destroy it and your supper. Further sealing the shell container with the other half of the turtle shell, and then layering more dirt over that, will create the ancient equivalent of a Dutch oven, casserole dish, cocottes, tetsunabe, Sač, Potjie, or Bedourie oven.
　「Shit hole cavity plugging with uninterrupted concentration」is a MALE HOMOSEXUAL. Lower elements of multiple plugged orifices with bent penis are「dragonfly」animals that possess a most remarkable ability for「uninterrupted concentration」and wild sexual antics (see related glyph):「Specifically, the dragonflies can screen out useless visual information to focus on a target, a process called selective attention. 'Imagine a tennis player having to pick out a small ball from the crowd when it's traveling at almost 200 kilometers an hour…. The dragonfly hunts for other insects, and these might be part of a swarm — they're all tiny moving objects…. Once the dragonfly has selected a target, its neuron activity filters out all other potential prey. The dragonfly then swoops in on its prey — they get it right 97 percent of the time.' Using a glass probe with a tip 1,500 times smaller than a human hair, the researchers measured the neuronal activity that enables such amazing aerial hunting…researchers weren't expecting to see the same thing in an insect that evolved 325 million years ago.」
