A sloppy mixed metaphor?
I thought it was more creative than sloppy. Don't forget that many ordinary phrases were once jarring mixed imagery. To "wear your heart on your sleeve" was coined by Shakespeare; we still use it because it "stuck" due to its unorthodox phrasing.
If you like your prose to be anodyne, then maybe you like what AI produces.
I thought it was quite an effective metaphor!
I'm learning to like 'em more, along with every other human idiosyncracy. Besides, it makes a kind of sense, the idea of some resonance occuring in one's gusset. Timber timbre. Flangent thrumming.
