UwU speech, also known as verbal diabetes, is the complete saturation of language with sweet and cute words, and or the replacement/repetition of letters within words with other letters to accentuate the childish and sweet tone, often the letter "w" being ruthlessly abused. Emoticons/Emoji usage may vary but if used generally serve to exaggerate the coma inducing sweetness.
Examples of UwU speech
1. "Hewwo Daniel, w-would you liek sum snuzzles? :3 <3 uwu"
2. ">~< thancc you honey cookie. (insert anime emoji with hearts) i twied me best <<3. "
The speech from Team america world police. At the end... you know the great one.
The greatest speech ever:
We're dicks! We're reckless, arrogant, stupid dicks.
And the Film Actors Guild are pussies.
Kim Jong Il is an asshole.
Pussies don't like dicks because pussies get fucked by dicks. But dicks also fuck assholes. Assholes that just want to shit on everything. Pussies may think they can deal with assholes their way. But the only thing that can fuck a asshole is a dick, with some balls. The problem with dicks is they fuck too much or fuck when it isn't appropriate. And it takes a pussy to show them that. But sometimes pussies can be so full of shit that they become assholes themselves. Because pussies are a inch and half away from assholes. I don't know much about this crazy crazy world, but I do know this. If you don't let us fuck this asshole we're going to have our dicks and pussies all covered in shit.
