The mascot for the social news website Reddit, mainly depicted as a short white alien with orange eyes and an antenna.
Just imagime if Reddit was actually designed by aliens in disguise, and Snoo is their leader.

Kinda like a shart. But in this instance the motion emerges as a result of the muscle change caused by a sneeze, hence the name: sneeze + poo = snoo.

Hard to believe possible I know, but I've seen it happen. It was awful.
*Al enters office from adjoining warehouse looking gleeful*

Al: "You're not gonna believe this... Jay just had to go home!"

Shezzer: "What? Why?"

Al: "He just snooed!"

Shezzer: Gross! That's a food-safe environment...

To rub noses with either a partner or lover, or a much loved pet animal, in an affectionate way, like the Eskimo kiss but with more gentitlity- unless it's a 'woodpecker snoo', which is a much faster, slightly more aggressive (but still pleasurable) action. Can also be the pet name of the person you regularly do it with.
"Oo oo oo, I wanna snoo with you"

"You are my snuvverly snoo"

"Snoo with that flibbly woo"

A real creature, they are close relatives of the Blobfish, though Snoos do not live underwater, but in fact on top of the clouds. Literally. There are many different types of Snoos, like the Snooba family (Snoobini, Snoobette), Snooshie family (Snooshette, Snooshini) and the Flob family (Flobette, Flobini).
The Snooba family have large noses, blue and purple birth marks, pimples, moles and freckles. They are a pale pink, to reddish pink, to peach pink to salmon pink. Snoos live in Helvenworld, where there are many cities, towns and states, most of them named after Snoo families. The capital of Helvenworld is Helvenville, in the state of Helven.
Ylil: 'Gosh, this trip to Helvenville's taking ages!'
Enirehtac: 'Why of course it does! It's all the way up in the clouds! Read a book if you have to.'
Ylil: 'Wow, the Snoos must get car sick . . .'
