To chauffeur someone around, particularly an old lady, so that she can run errands. (Originated from the name of the black man, Hoke, in the movie Driving Miss Daisy.)
Man 1: Hey buddy, you wanna go golfing Saturday?
Man 2: I can't... I gotta hoke my mother to the hairdresser.
Very similar to a joke, a hoke is a half-joke. Like when you are trying to tell someone something and they respond with an insult, so you make a joke of it. It is most commonly used in those awkward circumstance when the person you're talking to makes a complete "prick" comment.
Tim: Hey did you see that Glee episode last night?
When in conversation someone says something beyond good taste. Something said that is mentally disturbing to others. Just going too far. You hoked it!
Jim "Stacy is feeling sick after partying last night."
Don "yea, I heard she defecated all over the bed last night and she threw up green slimy shit all over Dave's phone."
Jim "Dan, you just hoked it! I am trying to eat here!"
