Definition of snag ?

A snag is the humble hero of every Aussie barbie—just a sausage, but treated like a national treasure. Doesn’t matter if it’s fancy or cheap, burnt or barely cooked, a snag on bread with sauce is peak Aussie cuisine. It’s the first thing to run out at any barbecue and the last thing anyone admits to burning. If someone forgets the snags, that’s a crime against humanity.

He forgot the snags again—the galah.
