go on tick

To purchase something on credit. "Tick" is short for "ticket," a note that showed one's debt (although this practice is less common today). Primarily heard in UK. I had to go on tick for a bunch of last-minute purchases because I've already spent so much on this trip! Well, if you need groceries and won't get paid for another week, just go on tick. I went on tick for these things because I know my bank account is looking pretty bleak at the moment.
