idk, all the young adult girls ive seen pretty much talk the same way as young adult guys do so far in a general context. I only pretty much seen this level of stutter severity (if it exists in text form anyways) in patients with speech disorder or people who are traumatised. Or are very cold.
Even then, a stutter for 'p-p-p-p-p-p-p-p-please' and doing it with almost every single word in a damn sentence in a supposed 'cute' manner is like a bit of a literal erp fag moment.
stutter doesn't just have to the repeating of an imcomplete syllable in an obnoxious manner which is repeated with some other words in a sentence
It can just be complete syllables and multiple ones as well.
"I know--I know--I know a lot of information!" - multi-syllable
"W-we-we went under the bridge earlier!" - mix of complete and incomplete
Also, males are statistically 3 - 5 times more likely to suffer from a stutter as compared to females.
