Fair is foul

1. When 3 women with beards tell you that you’re gonna become king so you murder everyone you know and then get murdered by a caesarian man and a walking forest

2. when you think something is fair but then it turns out it’s actually not #plottwist

1.
WOMAN WITH BEARD 3: ‘and king thereafter’
MACBETH: ‘well time to kill’ *pulls out sword*
2.
person 1: ‘aw man i was forced to submit an application and now i’m gonna become a prefect’
person 2: ‘well fair is foul so ur just gonna have to deal with it’

Nerd Foul

To perform an activity that is considered nerdy, but in a fashion that is considered improper or incomplete to other nerds.

You made a Princess Bride reference by saying "You killed my father. Get ready to die." That's a nerd foul.

foul-duckery

Something that is not right in the mix. The story being told doesn't match up to what actually occured.

Did you hear about Lauren and Bartholemu? Sounds like there is some foul-duckery taking place!
