in cape breton gaelic it means generally party, but usually implies fiddle music and dance as opposed the seissuin where there were rarely dancers, but not as formal as a grand barn dance with hundreds if not thousands of dancers.

in the general sense the word is used just for party.

some times it was also used the mean competitive dancing but that's rare.

now some say it's scottish for an annoying insect pest that keeps you wiggling and writhing like a dancer.
