Sparkly, if a music group or a band has a gig, it means they have a date set up to perform. I having a hard time finding the correct words to explain it to you, but okay, here would be the dictionary version: a gig is a job, especially for musicians. Here are more definitions from the dictionary...but I think the one you're looking for is the one above.

at that site you will find the word gig, biscuitto.. mmm in Thailand .. we also have this word Gig.. but I think.. Huge huge huge different meaning.

Therefore, sometimes I think it has the same meaning as well.. I just don't know..

help

ohohmommio has it pretty much covered.

But, a gig is basically a job that's a one time thing. People mostly use it for musicians playing a show. But, you would also use it if you were, say a photographer and were hired to photograph a specific event. You'd call that a gig. You wouldn't generally use it to refer to an ongoing job that someone goes to every day.

ahhh now that I got it.. thank youuuuuuuuuuuuuu

thank you both of you very very much ... by the way.. your captain hat (is that the right word) is too cool
