I read this phrase in a visual novel:
"こいつが出かける前に、きっちり支度をしていきゃがらなかったからじゃねぇかっ！？"
I don't get what the "きゃ" means in this context. If it's short for "ikeba", I can't make sense of "がらなかった" ("didn't show any signs" of what? ) and if it's something different, I don't have a clue.
「していきゃがらなかった」 with a small ゃ
The "dictionary" form of that is:
「していきやがらなかった」 with a regular-size や
The components are 「する」、「行{い}く」、「やがる」 and 「なかった」.
For an explanation of 「Verb + やがる」, please read:
How to use the inflection "やがる"?
Thus, the sentence in question is in the Kanto tough guy speech.
"That's because this dude hadn't made proper preparations before leaving (home), ain't it?"
I didn't make it sound too tough, did I?
