What it means
To gobble something is to eat it way too fast and a bit greedy, barely chewing, just launching it down your neck before anyone can blink. It usually comes with a bit of side-eye, but it can also be said with respect when someone's absolutely smashed a post-pub takeaway. Not fancy, just vivid.
Usage examples
"Baz gobbled his pizza in ten minutes, crust and all, then reached for my chips. I said slow down, mate, you’re not in a speed-eating contest."
"He gobbled the whole packet of biscuits before anyone else got a look in, classic."
"Don't gobble your dinner, there's no prize for finishing first and you'll get hiccups again."
"You fully gobbled that burger, mate. I looked down for two seconds and it had vanished off the face of the earth."
"She came in starving after her shift and gobbled the chips before we’d even found the ketchup."
Where it comes from
This is old, standard English. Gobble shows up in the late 1500s and first copied the gulping sound linked with turkeys. After that it slipped naturally into the sense of eating fast and greedily, which fits the noise and chaos the word already carries in its belly.
