I’m reading this story knit.

“I’m easy meat for the rain drops that feel like small brooks running down my neck.”

I look for ‘meat’ in dictionary but find no mean but a kind of food.

Is it a mistake or another mean of ‘meat’?

and some other words … uhm…go wrong?

‘to be easy meat for’ is idiomatic.

In a near-literal sense it means it is very easy for them to feed on me.
When it is used where ‘feeding’ doesn’t actually occur, it just means I am easily beaten by them.

When things go wrong / when things go right…
when they turn out badly or well.
