If you've ever gardened, you know weeds grow super fast.

They can take over a garden overnight. But what does "grow like a weed" mean in other situations? Hey Dan, do you want to see pictures from my trip home? Oh jeez, I would love to, but... Great!

This is me with my little cousin, Arlo. Little?

He's taller than you! I know!

He is growing like a weed.

He's only ten. Does he have a beard? To grow like a weed just means to grow very quickly.

We mostly use this expression when talking about how fast children grow. And that's English in a Minute.
