What it means
A live wire is someone who never seems to power down. They're chatty, quick, full of bounce, and always halfway into the next thing before everyone else has caught up. It's mostly a compliment for a lively, exciting person, though it can also hint they're a bit much if you're trying to keep the room calm.
Usage examples
"Jess rocked up the boozer, necked a Jägerbomb, nicked the aux, and had strangers doing a pub quiz. Absolute live wire."
"Gran is eighty but a total live wire, dancing till midnight at the party."
"The classroom changed the moment that live wire of a kid walked in."
"Maya's a proper live wire, mate. Took over the fundraiser in five minutes and somehow got the grumpiest bloke there laughing."
"That little lad's a live wire. Turn your back for ten seconds and he's built a fort, started a game, and recruited half the street."
Where it comes from
It comes from the literal electrical sense of a wire carrying current. By the 19th century, English had started using it for people who seemed charged up, lively, and hard to contain. The jump makes sense straight away, since the image is all spark, movement, and a bit of danger if you can't keep pace.
