Meaning of 'He can't be bleat' in Witcher TV series song 'Toss a coin to your witcher'

Solution 1:

When you take the phrase "be bleat" on its own, it is meaningless in English. As you noted, "bleat" means a cry of pain or displeasure, typically made by a sheep, and of course no one can literally be that cry of pain. But as with many song lyrics, that doesn't mean it's actually meaningless.

Essentially it's a shortening (or "contraction") of "he can't be forced/made to bleat" ... or in other words "this guy is so tough nothing ever will make him cry out in pain" ... unlike a sheep (which is a commmon symbol of weakness) ... or a bard for that matter ;)

This references the scene in the show where the character was being beaten up, but never asks for mercy (for himself; he tries to save the bard, and so the bard writes the song in appreciation).

But as you noted, it's a very odd contraction, and was presumably made as wordplay on another common phrase: "he can't be beat." The un-contracted form ("he can't be made to bleat") doesn't sound nearly as close to "he can't be beat", thus the contraction.

This somewhat silly wordplay fits the theme of the rest of the song, which is not only silly, but downright anachronistic at times (eg. "he thrust every elf, back up on the shelf" makes reference to the modern "Elf on a Shelf" toy ... which presumably doesn't actually exist in the world of Witcher).

Solution 2:

It referred to the moment in the actual incident where the elves threatened the Witcher and Geralt basically said "kill me now." As opposed to the bard, who was busy bleating. :)
