What it means
Used when someone's moving slow, dragging behind, or taking ages while everyone else is already getting on with it. You hear it for walking, getting ready, replying late, even turning up with zero urgency. Often comes as stop lagging, which is basically a quick little tell-off to hurry it up.
Usage examples
"Oi, stop lagging, mate, we’re gonna miss the last train. You’ve nailed three Greggs already. Shift it or I’m off without you."
"Stop lagging at the back of the queue and grab the brews, mate, the table is about to be cleared by the lad with the bell and we will have to start the whole quiz round from scratch again."
"My cousin has been lagging in the family group chat for two days, we sent the new gender reveal video on Saturday and his only reply is the thumbs up emoji at half past midnight on the Monday."
"Bro, stop lagging and get in the Uber, everyone's in there sweating already."
"You're still lagging on that reply from Friday, man, the chat's moved on and had three new arguments since then."
Where it comes from
It comes straight from the older English verb lag, meaning to fall behind or move slower than the rest. That word's been in English for ages. Later, gaming and internet talk gave lagging a fresh kick, tying it to delay and slow response, which helped push it harder into everyday slang for people moving slow.
