fired for pussy breath?

So I came into work today after enjoying a house warming party the night before, and one of my managers comes up to me and tells me I need to clock out and go home, adding "I think you know why". I tell him I actually dont, and he says that a coworker complained to him that pussy was smelled on my breath. I dont eat at work, or before work, and it was apparently so faint that pretty much everybody I asked afterwards didnt notice it at all, not to mention I didnt get any complaints from co-workers or customers. I now have a meeting with my boss tommorow morning over this incident, and im just wondering wether he can fire me for eating pussy the night before, and what should I tell him, as I didnt do it on company time. Also, if it matters, I work as a salesperson in electronics.
