"Dearg Druchtach", you say.  "WTF?  I can't even pronounce that."

“Unbeloved is the horseman that comes there,” said Lugaid. “It is Conall the Victorious, mounted on the Dewy-Red. The birds thou sawest above him are the sods from that horse’s hooves. The snow-flakes thou sawest specking the plain before him are the foam from that horse’s lips and from the curbs of his bridle" . . . . When Conall found that he prevailed not, he saw his steed the Dewy-Red by Lugaid. And the steed came to Lugaid and tore a piece out of his side.

 I promise I won't tear a piece out of your side. 

Beyond that, all bets are off.
