Irish slang meaning to succeed brilliantly or to do exceptionally well — implying you're so powerful and capable you could run on diesel fuel. The phrase has a rough-and-ready, working-class energy to it, suggesting not just success but a certain hardy competence. Used both as a declaration of personal triumph and to compliment someone else's achievements, it captures the irreverent, colourful way Irish English turns everyday imagery into vivid expression.

- suck it and see67%
Suck it and see is a cheerfully pragmatic British, Irish, and Commonwealth expression meaning 'try it and find out' — a call to experiment rather than overthink. It has the earthy, no-nonsense energy of someone who'd rather do than deliberate. The phrase comes from the era of picking up an unlabeled sweet and tasting it to find out the flavor, but it has since spread to virtually any situation where the only way to know is to give it a go. Mildly suggestive in tone but widely understood as innocent.

- give it socks63%
An Irish slang expression meaning to go all out, put in maximum effort, or fully commit to something.

It's energetic, punchy, and very much part of the Irish vernacular toolkit for expressing enthusiasm and determination.
