Understanding the usage of だらけ


I've come across this in the following sentence:

> 油断だらけのこの背中

油断 means "reckless" or "negligence" and だらけ means "full of" or "riddle with".
While I can decipher(?) the meaning of the sentence as a whole to mean "This
back full of openings" or something like but I can't fathom the meaning of the
combination 油断だらけ.

Is it simply "Riddled with negligence"? Can I use だらけ with other words like 穴
to say that something is riddle with holes or 虫刺されだらけ to say that something is
riddle with bites from insects?

Thanks




As far as the literal translation goes, yes, it is simply "this back riddled
with negligence". Grammatically, -だらけ is a suffix that forms a no-adjective.
Like "riddled with ～", "～だらけ" is used with many undesirable (and usually
countable) things, like so:

  * 欠点だらけの人
  * 傷だらけの顔
  * この文章は漢字の間違いだらけだ。
  * 穴だらけのセキュリティー

A 背中 doesn't "have" 油断, and 油断 is not really countable, so 油断だらけの背中 sounds
like a little poetic/literary expression to me.

On the other hand, these are incorrect:

  * ❌水だらけのプール (say 水でいっぱいのプール instead)
  * ❌笑顔だらけの顔 (say 笑顔でいっぱいの顔 instead)
