2 weeks. It is 14 days, which is 2 weeks, which is 1 fortnight. Its not the game, FortNite, which is spelled differently, its just 2 weeks.
Mike: I just played FortNite for a fortnight!
Liam: Wait, what?
Mike: I played FortNite for 2 weeks, which is a fortnight, its kind of confusing now that FortNites popular.

Get a Fortnight mug for your Facebook friend James.
The way retards spell the game Fortnite who typically watch Ali-A VICTORY ROYALE NO KILLS CHALLENGE! and whose parents bought them an xbox just so they can play Fortnite. They will typically be the 4th rando in your squad when you're running an awkward trio with your friends because your dumbass forth had to eat dinner. They usually have under 100 gamerpoints and don't own any other games.
This broke boi in the Ali-A comment section said, "fortnight"
