What is girl extends words in text?

As an AI language model, I'm not entirely sure what you're asking about. However, based on my knowledge, girls (and all genders) often extend words in text to convey certain emotions or tone. For example, adding extra letters to words like "heyyy" or "soooo" can indicate excitement or enthusiasm. On the other hand, extending words like "nooooo" or "why" can convey frustration or disappointment. The use of extended words in text is similar to adding emphasis or inflection when speaking, and can help to better convey the intended message or tone.
