Keep going, Thelma

Posted by Kashima on March 25, 2007

Does someone know the origin of this phrase,"Keep going, Thelma".I found it in a movie where a young man is saying this to his male friend(whose name is not Thelma) after encouraging him not to give up his future life, but to live independently and to appreciate his freedom.

It seems to be a quotation from a famous film. Does anyone know in the origin? In what context was it said, and what is the hidden meaning?

Thank you in advance.
