The "smirk" emote depicts a green, blob-like character with a smug, self-satisfied expression - one eye squinted/winking and a small smirk on its face. It's used to convey smugness, self-satisfaction, playful arrogance, or a "I told you so" attitude in chat. The emote represents that feeling when you're feeling clever, confident, or slightly cocky about something.
Origin
This appears to be a custom emote that follows the style of popular "Okayge" or "Pepega" derivative emotes in the Pepe/frog meme family that are common on Twitch. The green blob character style became popular in the late 2010s as streamers and communities created their own variations. While the exact upload date and original creator of this specific "smirk" variant would need to be verified on 7TV, FFZ, or BTTV databases, it follows the established tradition of emotion-based blob emotes that gained traction around 2018-2020 when custom emote culture exploded on Twitch.
