A Jonny Cash Tribute is experienced the morning after excessive drinking and eating unusually hot food, usually laced with chilli etc. Involves long periods spent on the bog with red hot molten shite dripping out of your ring piece, leaving the sufferer with a 'Ring of Fire' i.e. stinging anus. Hence a tribute to Jonny Cash
"Christ I spent an hour on the bog this morning doing a Jonny Cash Tribute after last nights vindaloo"
