I don't know if I'm doing the right thing, but AI hasn't been able to help me with this. My friends constantly use English terms when talking to each other. My native language is Turkish. They constantly use words like based, lowkey, peak, and looksmaxxing. AND I DON'T KNOW WHERE THEY SAW IT OR LEARNED ABOUT IT. I know I'm doing LARP. Can you explain this by using these words in sentences?(I accept all commonly used words you know, except for the words I've given)
