It looks like you’re asking about the phrase “in my defence” or a similar wording. It means “to explain or justify my actions” , usually when someone wants to soften blame or give context for what they did.

What it means

  • In my defence, I was late because the train was delayed.
  • This means: “Here’s why I’m not fully at fault” or “Here’s my explanation.”
  • It can sound mildly apologetic, defensive, or humorous depending on the context.

About “fed all my defence”

That exact phrase doesn’t look standard in English. It may be:

  • a typo,
  • autocorrect,
  • or a misheard version of “in my defence.”

If you saw it in a post or chat, the intended meaning is most likely the same: the person is defending or explaining themselves.

Simple example

  • “Fed all my defence” → likely intended as “in my defence”
  • Meaning: “Let me explain why I did that.”
