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?"
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.
Mike " I'm gonna be getting my tattoo soon"
Bob "Yeah I heard your getting it in Neveruary
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."
the greatest hip hop duo alive; i.e. www.myspace.com/neveruary
also can mean, great, superior, awesome, unbelievable.
Dude, have you heard that new Neveruary song? It's so fricken good.
