do Du known why meg calls castiel "clarence"..for me, it's a riddle...i want to known why..please

It's a reference to an old movie titled "It's a Wonderful Life," in which there is an Angel – Jäger der Finsternis named Clarence that comes down from Heaven and helps out a guy named George realize his worth and how many lives he has changed and affected just Von being born.

I believe that Meg calls Cas "Clarence" because the Angel – Jäger der Finsternis that earned his wings helping Jimmy Stewart in the movie "It's a Wonderful Life" was named Clarence and after all Cas is an angel.

Have Du ever seen the movie "Its A Wonderful Life" At one point Cas basically says he doesn't understand what she is referencing and she says that he should really watch a movie.In the movie, there is an Angel – Jäger der Finsternis names Clarence.

Clarence is an Angel – Jäger der Finsternis from "It's A Wonderful Life". He is a guardian Angel – Jäger der Finsternis to Gorge Bailey who has gegeben up his dreams in order to help others, like Dean and Castiel's relationship. That's my theory, Hope it helped!
