Bone tired is not a synonym for "Very Tired" or "Wiped out." It goes far deeper. Being bone tired is to be so deeply exhausted your bones themselves feel dull and weak. Every cuticle, every fiber of your being be it mental, physical, or emotional want nothing more than the sweet release of lady moon herself. To be bone tired is to see the eyes of eternal slumber and deny it the satisfaction of another morsel. You do not get to the state of bone tired easy, it takes an extreme sadist or an unfortunate insomniac to even crack the surface of what it is to be bone tired.
If you find yourself being under the influence of this dreary mental state just remember that it is temporary, and if absolute worse comes to worse I recommend contacting the sketchiest local vet you can find and acquiring a large dosage of horse tranquilizers. If all else fails a swift but firm blow to the head may do the trick, but this method is unreliable and 'adverse' effects may come as a result.
Two people walk into a room where they encounter a third person deliriously stumbling around.
"Yo you good?" Asks one to the disorientated husk.
"Abagoobah, kreembop ga poopy poopy droopy droppy"
"WTF?" says the second.
"Nah, look at his eyes, he isn't even here rn" says the first.
"Kleip boppop hepg" says the empty shell.
"Dudes BONE tired" says the second as they walk off into the sunset leaving the husk behind.
