Like instead of using codewords for illegal things, use codewords that are known to get you flagged for dumb ass everyday things. Like instead of “is dinner ready?” you could say “are you done cooking the meth?”. Instead of can you go to the store to get eggs say “Did you get the 50lbs of ammomium nitrate?” Maybe don’t say stuff that could actually be interpreted as a threat, but your personal fed would probably stop even considering what you’re saying after a while.
