I smell red flagsPosted: May 4, 2018
This is a congruent conflation of “smell trouble” and “red flag(s)”, both meaning potential or imminent danger. “I smell a rat” (suspect someone is guilty of deception or betrayal) might also be in the mix. Of course, those red flags around gas leaks seem to conjure up this malaphor. A big thanks to Tim Geier who overheard this one!
