I haven’t seen anyone say “No Homo” who wasn’t slightly homophobic lately tbh.
Pause I feel is more neutral. But I have deviated from using those words/setting up those jokes lately
Those saying were always mostly insecurity disguised as humor or anger imo so I think they're corny. Kind of always have.
I don't think it's offensive but I think use of it reflects insecurity
Edit: insecurity when you're correcting something you say
