I saw it used in this context:
I am also fully capable of typing in complete sentences; descriptive gauntlets just seem more efficient.
Please explain the idiomatic use in the above sentence.
A secondary definition of gauntlet from Merriam-Webster:
My guess is the author was trying to employ this meaning of gauntlet as ordeal but used it so loosely it became difficult to follow. The phrase in question, beginning with "I am also fully capable of typing in complete sentences," follows a list of fragmented descriptors. The author probably meant to be clever when he referred to the list as a "descriptive gauntlet," intending to paint the picture of it as a kind of "ordeal" for the reader as if they were being clubbed with each of the descriptors in rapid succession.
The phrase means little to me out of context. I suspect that either there is some sort of joke that we're not privy to, or that the word has been used in error (i.e. a malapropism) - perhaps for epithet?
Google returns only three hits for this phrase (apart from on this site!):
... which is the source of your quote and doesn't provide a lot more detail (though it's consistent with being a mistake for something like epithet).
from a gaming site, which is clearly using the term in the sense of throwing down the gauntlet i.e. issuing a challenge (usually for a competition or fight). This sense of gauntlet doesn't really make sense in the quote.
And the third
..appears to be a page of complete nonsense.
So it seems fairly safe to conclude that this is not a common idiom :)
A gauntlet is also a gauntlet track, a kind of railing track. Used in a metaphorical sense, it it just means a long line or a long word. In modern Greek, for example, this idiom is used for very long and usually unattested words or proper names.
It is an ironic statement, saying that, even though the person speaking can indeed type complete sentences, they prefer typing much longer ones because it seems -sarcastically- more efficient.
