3-5 Business Days 

Commonly used phrase in Hypixel and Hypixel-related communities to represent something having an undetermined amount of time, that's likely to almost never happen or take a very long time.

It is said to have originated from the "Wizard Tower" of Hypixel SkyBlock where the NPC there has been replying with the dialogue: "Hmm...something appears to be broken. Give me 3-5 business days to fix!" for the past ~2.5 years and counting.

Friend: "When is x coming out?"
Me: "3-5 Business Days"
