NNN 

Abbreviation of "nah, nah, nigga". Allowing someone to know that in fact, they have it all wrong. While its meaning shifts based on the context, it is generally used as a retort following an incorrect statement, especially one made in jest.

Arthur: Man, what happened to rap after The Chronic? All downhill.
Lester: NNN, it's all good, Dre's still got it!

Rupert: Yo Leroy why was you actin like some kinda jive turkey at da club?
Leroy: NNN dat shit was on pointe. Bes respek.

No Nut November is when a male goes a whole month (30 days) without masturbation.

'You gonna try NNN?'
'Yeah, but I probably wont be able to do it.'

NNN~Also known as No Nut November~ is a competition that is held during the whole month of November, and yep! You guessed it! If you DO take part in NNN then you are not, under any circumstances, allowed to:
•Have sex
•Masurbate
•Cum
Etc...
However... you are allowed to watch anything & some people have extended their NNN time by saying they are not allowed to be sexually active for the entire November, & yes, they are not allowed to have any boners. There is no second chances so if any of you males fail then own up to it & don’t lie!

My cousin tries to do NNN but fails miserably, he couldn’t last a week

You can nut twice as much as you could in the other months.

Nonstop Nut November. A variation of the infamous No Nut November (NNN). Nonstop Nut November is a series where you partake in daily consumption of nuts (in whatever shape or form) for the entire month of November.
