Fort Night Stand 

A take-off on a "one night stand." A casual sex-based fling lasting a short period of time, usually around a couple weeks.

Steve-"What ever happened to that Jersey girl you were talking to?"

Sean-"Oh, that was over quick, it was just a fort night stand."

Fort Night 

The way that 40 year old mothers spell Fortnite, a game that’s not nearly as good as Minecraft.

”Son what are you playing?”
”Just some Fortnite.”
“What is fort night?“
“Look it up on urban dictionary, mom.”

Fortnight 

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.
Liam: So you played FortNite 14 days straight?
Mike: Yep, for a fortnight.

International taco fortnight 

International taco fortnight originated around 2012 in the Monterey Bay Area of California and is an annual festive event to celebrate tacos and Mexican cuisine in general, lasting one fortnight (or longer if desired). One is encouraged, but not required, to consume tacos on a daily basis for the duration of this event. Documenting your activities relating to this event on video or otherwise is encouraged, however frowned upon by some as "yet another image of food". The exact date of this event fluctuates and typically is announced a few weeks ahead of time.

I just ate three whole cheese tacos to celebrate international taco fortnight and now I feel sick.

fortnight 

Fortnight is a word the English say instead of saying Two weeks.

"I am going away for a fortnight"
