I heard a woman say this who was in a church plant where she was positioned as co-pastor with her husband. Normally, the version of this teaching I had heard and read growing up in the AOG and reading Pentecostal and Charismatic stuff was that if a word (especially about your calling) is not confirmation, don't accept it, or don't act on it, or something a little less extreme that 'It's junk.' There is also the teaching that if a prophecy doesn't 'bear witness with your spirit' to reject it. We can discuss the milder variations of this teaching.
