I had my friend write this for me after she said it. "Se Americain ou ye sorry ou nan pointe bouche ou". She said it means that I'm not sincere. Can you explain this for me? Thanks.

She is right about the meaning
..nan pointe bouche ou (written: nan pwent bouch ou) - at the tip of your mouth (meaning not from deep within)
as far as the sentence "Se Americain ou ye sorry ou nan pointe bouche ou" it means "You are American, your apology is not sincere"
Sorry to hear that she's got some bad sentiments toward you.
