The automatic response from many online chat users when asked "what's up?", "what's happening?" or any variation. The most annoying, pointless and ridiculous response imaginable. NM meaning "Not Much" and lol "Laugh Out Loud", insinuating that by replying nmlol, not much is "up" or "happening" and for some reason this deserves a "lol". If someone replies with "nmlol" it is recommended you immediately leave the conversation.
You: Hey man, what's up?
Friend: nmlol
You : ...
Friend: What?
You: I fucking hate you

David: "Dammit, I laughed at her niplol"
Jarrod: "Nice one derp."
While our lifespan is the number of years we will live, our healthspan is the number of healthy years we will have and our sexspan is is the number of years we will continue to be healthy enough to continue having an active sex life.

Sometimes doubled or tripled, and possibly said in a sing-songy voice for added comedic effect to imitate a muted trumpet, which is how the meme originated.
