What is the meaning of ハリ倒したらァ!

Question

ヤキ入れて追放に決まってんだろ！ハリ倒したらァ！

What is the meaning of 「ハリ倒したらァ」 here? As far as I am aware 「～らぁ」 can be a change from 「～るわ」 holding a meaning similar to 「～るよ」 as in this question: What does 「ことにならあね」 mean?

Assuming that this is such a change, that would make the underlying sentence「張り倒したるわ」, and my best guess is this would mean 「張り倒してやるよ」 but I really don't know. What is the actual meaning here?

Answer 1

It's short for 張り倒してやるわ.

• -てやる contracts to -たる. For the meaning of this やる, see What does てやる mean when it is not used for giving? and What does the word 「やったる」mean?
• This やらぁ is perhaps originally やるわ (where わ is a masculine sentence-end particle), but it's now fundamentally a distinct sentence-ender used by rough speakers. It's similar to やるよ, やるぜ, etc., but much rougher. They also say ならぁ (~なるわ), but they don't say 取らぁ, 知らぁ, etc. I don't know why.
