1. Gay men getting home and nashing after meeting in a bar.

2. "I like that report that you put together for the GM", male 1. "I thought it was ok but I can never produce one as good as yours", male 2. This tyype of "flirting" indicates that two otherwise straight men would like to be nashing with one another in the copy room.

Then a lame joke ensues and they talk about the hobby that they pretend to have in common (e.g. yachting)

complaining continuously and loudly on an issue based on a confused understanding, and minimal knowledge, of the underlying issues.

Nashing is exactly the same at Rick Rolling. You post a link to a Nash Grier youtube video, vine video, or instagram picture, in order to get the same result as Rick Rolling a person. This also works when using a vine video, youtube video, or instagram picture of one of his friends as well.

Nashing was created by a Tumblr user on Feb. 2nd, 2014.
Person A: Hey Jackie! We are Nashing Steve and Julie!
Person B: Yeah we are! Wait they responded! *starts to laugh*
Person A: *Laughing* You should get in here and read this!

To nash is to rub one's nipples against another being or object sensually or threateningly in a matter of reflection, release, or fun.
"Oh jeez!" "Oh man!" "That nashing did the trick!" "Well, see ya same time tomorrow, kid."
