...  Ah, this pains me so much. Keep in mind Systemic Dagger Dragon was translated a long time ago, and Bushi's been pretty bad on that lately... Also, I'd like to point out that "dancemarkable" is nonsensical, and phonetically identical (in Japanese at least) to "Danse Macabre", which actually has a meaning... albeit in French. "Danse Macabre" is French for "Dance of Death"

And Raijin, if you want proof of the phonetic similarity... I'mma go with "markable" and "macabre", due to "dance" and "danse" being indisputably identical.

"Markable" in Japanese phonetics would look something like this:  "maa-ka-bre" mostly due to them generally not pronouncing any "r" that follows an "a" (I'm generalizing, don't attack me for individual exceptions) and the l/r confusion, seeing as they don't have an "L" sound in Japanese. On a side note, this is exactly how to pronounce "macabre", and Systemic Dagger Dragon and Systemic Dagger "Black Edge" both said "macabre" in the anime.
