How to Adapt Drunken Fighting Skill from 3E to 4E

[binn05]

As the title says, how can I adapt drunken fighting skill from 3E to 4E?
One of my players want to play a Martial Artist in a DF campaign that will play in the next months and would like to use that skill?

I looked at Martial Arts 4E, and there is nothing like that.
Since I bought the book on last year's sale, I'm not familiarized with the ins and outs of MA 4E.

Any help?

Edit: Forgot to add what the skill does in 3E.

Roll a Quick Contest of Drunken Fighting skill vs. opponent's IQ. If the player wins, his enemy is at -1 to hit or defend during the turn (player's choice) for every point by which he lost the contest. If the player loses, he suffers the penalty. On a tie, combat is resolved normally. Experts (Skill 18+) can fight while intoxicated without penalty.

If I can't post text from the books, please tell me so and I will remove it.
