Hello,for the part where phoebe spoke saying Doy,””probably right before she lost it”,it literally meant that was a stupid question and for chandler who said “you don’t get a lot of doy this days , it means (the word doy was old fashioned). Present day slang of form can also mean ‘duhhhh’ 😅 . I am a huge fan of friends too.

Thank you! I was thinking about "duh"))) yes, the Friends is really good for practice English ☺️
