Me: “Could you come back this afternoon?”
Her: “I don’t know – I might could.”
Oh no! I’m so sorry you had to hear such an abomination of words. Yes, “might could” is a rather common one here in the south. As is “where you at” and “Have you ate yet?”
Ha ha, David Crowder Band (my fave) uses ‘might could’ in a lyric too… atrocious.
