I've seen a lot of various 3 word combos mostly revolving around shit and shit adjacent coloured eyeware and that was my thought as well but one thing I think everyone's missed is that it you want to try and stick to that template so it's recognisable as the antonym for the phrase but still change enough of it to be clever, we should change tinted as well and I think "tainted" is perfect since it sounds almost the same and has a similar meaning in context but still adds it's own negative connotations.

"Shit tainted glasses" is the chef's kiss in my mind. Unless anyone's got something that means the same or almost the same as glasses but also adds additional negative overtones.
