The fan nickname for Snivy, a fictional species from the Pokémon franchise that made its debut in the 2010/2011 Nintendo DS video games Pokémon Black Version and Pokémon White Version as Pokémon species #495, serving as the Grass-type starter Pokémon for the Unova region.

This leaf-tailed Pokémon quickly gained significant popularity on the Internet for its smug looks, hence the nickname. It's been called at times, "the new Mudkip", and "Smugleaf" became a sort of Pokémon variation of trollface. There were also references made about its design being similar to that of "Excalibur" from the popular anime series, Soul Eater.

May 15 Word of the Day
A few weeks ago, no one had “cheugy” in their vocabulary . Now everything is saturated with the word. It’s in our heads. It’s in our homes. Everyone is asking: “Am I cheugy? Am I a basic ass bitch? Am I GUILTY of being cheugy?”

The proliferation of cheugy in the mainstream discourse can only be attributed to one source: mental terror. It’s an orchestrated psychological trap to make you question your tastes and interests in the eyes of others.

You are not a cheug. YOU’RE PERFECT!!!!

It is very suspicious that the cheugy mascot is a Minion, a literal cyclops, a deformed
yellow panopticon in overalls ... do not let the all-seeing eye to control you. Be vigilant. Resist cheugy psyops.
Becca is another victim of cheugy psyops. I saw the garbage truck take all her Ugg boots yesterday. She even removed “I LOVE The Office!” from all her dating profiles. She’s unrecognizable.

The Grass Type Generation V Pokemon. It's not its officical English name, yet it has recieved the name Smugleaf due to it's appearance having a half-closed eye and a smirk. Due to it's popularity building on 4chan, it has bascically become the new Mudkip.

Internet user 1: "Not anymore"
