What is Neveruary?
1.
A period of time that doesn't exist. When speaking in the future, it means something will never happen. When speaking in the past, it means "a long, long time ago."
From season 3 of Making The Band:
P. Diddy: "When's the last time you saw Dylan?"
Chopper: "Neveruary."

2.
After months of being short staffed, we asked (sarcastically) when will the new hires start? Neveruary? It means a time when something is not going to happen.
If someone has been waiting on something and it seems like it isn't going to ever happen, but someone sarcastically comments..."It'll happen in the month of Neveruary."
