When someone or a large group of people cut their hair very short unexpectedly, usually used to describe a random wave of boys all getting the same haircut.
“Dude, mink disease is spreading like wildfire!”
“I know right, I can’t believe so many people are getting mink”
When everyone suddenly decides to get the same haircut/style, esp. short hair with shaved/short sides.
“Wow Mink Disease is spreading like wildfire! I can’t believe everyone is getting the same haircut!”
