Fortnite

A disease most commonly found in post-millenials, can cause many bad effects such as -

Uncontrollable distasteful dancing whenever something mediocre happens in your life
A sudden loss of money as you realise you spent it all on people that makes your disease worse as well as 'skins' so your virtual little self looks good when it dies every 2 minutes
Brain tumours, just because
Separation from your family
Bladder problems as you don't want to leave your computer
Not wanting to leave your computer
Becoming an egotistical twat
Ali-A

and Ligma.

The only cure is to get outside and do something with your life.
