Saying that something 'glows in the dark' implies interference, so unfortunately, within cryptography, it has become an industry term as well as metaphor.
Other examples are the 'mystery padding' in keccak vs sha3.

My main familiarity with it is from imageboard culture, where (mostly) reactionaries use it to accuse each other of being feds.

Given that "glows in the dark" typically refers to fluorescence[1], where does the interference comes in?
To say something glows means to suggest the US three letter agencies are interfering with it. If some cryptography glows, it means it's been compromised by US authorities. Glowies are the operators themselves.
