My son just rolled up looking like this and saying 
"Look mum, I'm a meat head!"
 
 
 
 He'd popped into the supermarket on the way back from work and bought some belly draught for himself, a kilo of chicken liver for me, and a load of free scraps for me to render down. I did well out of the deal too because he didn't want anything for the chicken liver except for me to give him a jar of paté when I next make some. 
 
 He says the meat is easy to carry like that because it conforms to the shape of his head. 
 
 Edit to add another photo.  He's removed 'my' stuff and put his stuff back on his head to leave his hands free to check something on his phone. He seems quite a convert!
 
 
 
 Second edit. He just left, with the meat secured in place with his headphones. 
 
 Really not sure what to make of it all...
