The xdding emote is a variation of the classic "XD" emoticon that evolved into its own distinctive Twitch emote. It features a distorted image of what appears to be a cat with human teeth displaying a devious laugh. This emote is used to express intense laughter, amusement, or hilarity in Twitch chat, often conveying a stronger sense of humor than the standard text-based "XD".
The xdding emote originated from the classic "XD" emoticon that has been used in internet culture for many years to represent laughter (a sideways laughing face with closed eyes). The specific image version seen here evolved within Twitch communities as a more expressive and humorous take on the original emoticon.
The emote is available on third-party emote platforms including 7TV (where one version was uploaded with ID 62e700220529159003a21db8) and BetterTTV (where it was uploaded by WideHDemotes with ID 635d1dfeed98a03da0ce2a84). It has become particularly popular in certain streamer communities, including that of League of Legends streamer Caedrel.

Variations such as xDDD or xxdd may also be used to indicate even greater degrees of laughter.
