What does Blewcallaphus mean?

Blewcallaphus meaning in Urban Dictionary

An exclamatory used once you answer the device and no you're on the other side line. Usually utilized after some skeptical "Hello's" have verified that there's in reality no one here. Reciting the phrase not only relieves some stress developed by the problem, but in addition acts as a code to allow the other person know you couldn't hear all of them, if they have been actually on the line and there's only difficulty with the connection. Hence making the reason of the abrupt say goodbye simpler.
