Ugandan Knuckles emerged in late 2017 as a VRChat avatar meme, a distorted version of Knuckles from Sonic the Hedgehog performed with an exaggerated accent and the catchphrase about knowing the way. Clips spread quickly through YouTube, Discord and Twitch in early 2018. The knocking version strips the voice away and keeps only the arrival gag, so it works even without the original dialogue. Similar door knock clips like batida na porta are used the same way, marking an entrance before a meme character appears.
