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."
The act of someone saying that they're gonna do something that they have no intention of ever doing. ie getting that sweet tattoo, asking that hot chica out.
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 sarcasticallycomments..."It'll happen in the month of Neveruary."
The month when you’re absolutelydefinitely 100% going to do those really important things you’ve been putting off. Actually, the worst possible month to get anything done.
