That phrase, "dede noself yes," is not a standard English idiom or a common phrase. It sounds like a playful, made-up, or possibly a slightly garbled version of something else.

Let's break it down and explore what it could mean, based on the sounds and words involved.
It Sounds Like a Child's Phrase or Gibberish
This is the most likely interpretation. The sounds are simple and repetitive:
- "Dede" is a common sound in baby talk (like "dada").
- "Noself" is a strange combination, but "no self" could be a child's way of negating a statement.
- "Yes" is a clear, affirmative word.
Together, it sounds like something a toddler might say while playing, experimenting with sounds, or being silly. It doesn't have a literal meaning but conveys a sense of playful defiance or nonsensical joy.
Example: A child might be playing with blocks, knock them over, and then shout "Dede noself yes!" with a big grin.
It Could Be a Misremembered or Misheard Phrase
Sometimes, our brains jumble words from songs, movies, or things we've heard. It could be a variation of:
- "Don't you doubt yourself, yes!" - This is a stretch, but the "d-d-d" and "self" sounds are present. It would be an encouraging phrase.
- "They don't doubt themselves, yes?" - A similar, more grammatical version.
- "It's the self, yes." - A very abstract, almost philosophical-sounding phrase.
Without more context, it's impossible to know for sure, but it's a possibility.
It Could Be a Meme or Internet Slang
It's possible this is a very niche or new piece of internet slang that hasn't gone mainstream. The phrase is weird enough that it could catch on as a meme, used to express confusion, agreement in a nonsensical way, or as an inside joke.
Conclusion
In short, "dede noself yes" is not a recognized phrase in the English language.
Its most probable meaning is childlike gibberish or a playful, made-up expression used for fun or to convey a silly, nonsensical mood. If you heard it in a specific context (like a song, a movie, or from a particular person), that context would be the only way to understand its intended meaning.
