I've been looking, but...

Nag.
Mic drop.

Nice! Good one. (I'm nodding.)
However, it may be worth noting that a meme, by its nature, might be navigating the reader to an answer that could be needling, mind numbing, or perhaps even nurturing.

Oh, N-verbs with -ing are allowed too?
Doh, I was just trying to limit it to a root word!

Good thinking! (Most do have an -ing suffix.)
There is one particular word I am hoping someone will find....

I SEE IT NOW, BROTHER
MY EYES HAVE BEEN OPENED
ALL HAIL THE VOID
AND THE NOTHING WHICH IT IS

Naming Napping that type of stuff so I changed your mind.

Indeed!.☻ But this is a meme, so look for the hidden joke.

Good ones! I reveal the hidden joke "answer" in another comment.

ROFL I heard Squidward's voice and his more-than-deserved sarcasm. Perfect response!

NVG

I could see that, even at night! ☻
I revealed the meme's joke "answer" in another comment.

NUG.

NUG! That could be a grunt (low man), a bud, or (the best one) chicken nuggets! YUM! I digress...
Excellent response, perhaps better than the meme's joke "answer" that I will now put in another comment.

After 3 weeks, it's time to reveal this meme's joke:
Nothing. That's it. "Nothing" is a word that begins with N and ends with G. N-o-t-h-i-n-G
That's the joke. Lame? yeah, I know. Please don't hate me. ☻
