Traditionally, there used to be rap battles, where Gaelic people got drunk and started to compete for the most insulting, humorous five-line poems having rhyme schemes, otherwise knowns as limericks, and the one who loses would have to buy the next round of drinks. A Scottish form of rap instrumental, "puirt a beul", was the predecessor of mouth organs. Rap instrumental was not influenced directly by the Scottish and the Irish because all its originators were African American.
