An uncommon (inexistant) mis-spelling of the phrase, 'Shits and gigs'. Shit sand gigs could be interpreted as jobs done at dodgy beaches, shit jobs involving sand, or
bad music at a
beach boys cover band music festival.
-- Oh no, Tracy said we were just doing it for
Shits and gigs, but she meant the upcoming
beach boy cover band festival in central coast!
- That sounds like a vast array of
shit sand gigs, as opposed to a bunch of laughs with the lads, a whole lot of banter and tom-foolery for the
shits and gigs.
