A guy who takes on a whole bar of beers by himself, like he's got a death wish and a taste for cheap alcohol.

At the pub, John downed 12 pints by himself. 'This is what Rambo does,' he said, slapping the bar.

Sarah's cousin fought off 20 beers alone. 'That's Rambo energy,' the barkeep said.

When the party started, Mark took on 15 beers like it was a battlefield.
