Why are people putting cola in their milk? Seriously, why?

This could very well be the grossest thing I've ever heard. Just stop.

I didn't know mixing your plain old milk with cola was a thing but trends it's 2019 and trends these days are getting harder and harder to understand.

I guess #milkcoke is trending on Twitter and Instagram I could understand if you're putting the Coke or Pepsi in an glass of ice cream but just milk?

I guess it's a question I'll never know the answer to but I could as another one. If yo're going to participate in something so ridiculous would you rather mix you milk with Coke or Pepsi? I guess I could take it one step further and ask if you would use regular milk, almond milk, lactose free milk, or oat milk.

What do we do here?
