"Hello, 'please call me...' Trope." "Please, call me Tropey." A stock phase in which a character is adressed by his/her full name, but then is told the exact words 'please, call me...' before inserting his/her prefered nickname. A sister trope of Don't Call Me "Sir" (For when a character simply objects to being called sir) and Do Not Call Me "Paul" (Which is when a character hates his/her name and will be vicious in correcting someone or simply ignore them).
Hello, Unknown Troper. You'll need to get known to lend a hand here.
