Gig is a thai word , not english but sounds english .in thailand we use this word for name people like " Sumo Gig "
Have you ever heard this name in some thai tv program . he is a host of a varity program .
The meaning of gig that you understand might be right because in my oppinion I've heard some defination
of this word (and I already forgot ,found in thai newspaper)for example ..they have rules for people who want to
be gigs ...like a kinda cheater or having affair without relationship and some way they said just a little bit of
relationship but not so deep and nothing more that chating with. But it could be only one way that I try to explane
or both anyway you can guess what is its meaning by yourself .
