Anyone heard this term yet? It's a first for me and the men who are "here to help" basically said it's anything that doesn't fall under accident or incident.

Appendix A lists a bunch of stuff. Maybe this is what you are looking for.
to file a NASA ASRS report tonight. You don't even have to pay for a stamp. The only thing it will cost you is a few minutes. Also, regardless of what happened or the relationship to you professionally, filing the report will give NASA more data upon which they can improve the aviation safety system. So, you're doing a good thing whether it benefits you personally or not.
