Get the Dirty Fortnite mug.
When you get 15 Fortnite wins in a row and then spread your seed around your room so much, you lose all energy in your body and go into a 15 year coma because of Fortnite
Person 1: What? Where am I?
Person 2: You did a Dirty Fortnite 15 years ago...
Person 1: Ah that was amazing
