: Anyone? Origin? Thanks in advance.

Merriam-Webster Online:

A definition for blue:

7 a : PROFANE, INDECENT b : OFF-COLOR, RISQUé

Main Entry: blue streak
Function: noun
Date: 1830
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".
