A "Suppledunk" or "Suppledunking" is the act of puffing your lips out and simply placing them into a full glass of whiskey, not taking a drink, just letting your lips slowly suck up that sweet, sweet mother's milk.
"That 18 year was so delicious, I couldn't drink it. I had to SUPPLEDUNK it."

"I'm taking a trip to Islay this year. I'm overdue for some serious SUPPLEDUNKING."
