Going for a grog run and paying with coins.

Shortened to 'skummer'/'skumming'.

(If you're purchasing rum, it becomes a 'rum skum run', which becomes increasingly difficult to say each time you go for one.)

***
Dude 1: man, grog shop closes in 15 minutes and I can't find my 20 bucks!

Dude 2: fuck the 20! grab all the coins you can, we're going for a skum run.
