The Doctah is a
tv term related to Scifi
Brit series, Doctor Who. Whooligans use this word because the pronounciation of "the
Doctor" especially by the Tenth and the Eleventh became "scottish", so to joke on it they say Doctah.
Oh, for Gallifrey's sake, this fish fingers and custard were
cooked by
Jenna like the Doctah had done on tv!
