To drink for days on end in cheap pubs populated by 'rastlers' (servere alcoholics)
rastling, rastler, rastled.
"I went out rastling last week and rastled for three days! I told myself I wouldn't rastle again this week, but look at me now: I'm in a shit pub, surrounded by old rastlers, Snoop Doog is on the jukebox, and I'm gonna be rastling 'til the cows come home."
