Can you use it in a sentence? That will help us to answer you better. There is a meaning of "gig," which is a short-term job for a band or other entertainment group. You could say, "Our band has a gig at the club at 8 o'clock." Is this the meaning you were looking for?

While you probably heard the word in the context of a music performance (as Nancy said), a lesson commonly used answer is the tool used to hunt for some animals in ponds or lakes. http://en.wikipedia.org/wiki/Gigging

перевод сильно зависит от того, где Вы его нашли

thank everybody!Yes,you're right in context it would be simply to get definition of that word,but unfortunately I forget where exactly I heard it.

It can be used as reference to a music job or any job where you have to travel. You could be a carpenter and have a 4 day gig out of town on a house restoration for example. Younger people also use it to refer to a stationary job. 'Dude! I just scored a gig at Walmart!'
