: Anyone? Origin? Thanks in advance.
A definition for blue:
7 a : PROFANE, INDECENT b : OFF-COLOR, RISQUé
Main Entry: blue streak
1 : something that moves very fast
2 : a constant stream of words
Since blue can mean profane, the stream of words could be one epithet after another. This would result in "cursing a blue streak".
