Digger

Similar to a negger. Someone who repeatedly passively-aggressively pries into or comments on your life/appearance/choices etc. Usually in the form of veiled insults and/or backhanded compliments. They are generally trying to get a rise out of you, as they specifically make what they say sound innocent enough so as to appear like the victim at any retaliation.
The type of person to say something like: "oh, are you sharing with someone? That's alot of food..."

Person 1 : "How was the trip to the in-laws?"
Person 2: "A nightmare, MIL just kept asking questions about my promotion and would not shut up about how, god forbid, I'll make more then my husband."
Person 1: "Jesus, she sounds like a digger."
