crook (one's)/the elbow
To drink alcohol, perhaps excessively. Come crook your elbow at the bar with us tonight! If you're this hung-over, you must have really crooked the elbow at the party last night.
crook one's elbow
Also, bend one's elbow. Drink liquor, especially a great deal. For example, Bill is known to crook his elbow now and then, or Uncle Joe rather overdoes it with bending his elbow. Both slangy expressions allude to the motion of lifting a drink to one's lips, which involves bending the elbow. The first dates from about 1820, and the second from about 1900.
