CONTRACTION:

TONE:
やっちゃった is lighter than やらかした. It suits minor slip-ups and has a self-deprecating, sometimes cute quality:
- やっちゃった: "oops" — minor mistake, somewhat playful
- やらかした: "I screwed up" — bigger blunder, more serious
〜ちゃった PATTERN:
This contraction is widely used beyond やる:
- 食べちゃった: I ate it (and maybe shouldn't have)
- 忘れちゃった: I forgot (oops)
- 壊しちゃった: I broke it (accidentally)
- 言っちゃった: I said it (slipped out)
The pattern always implies the action happened unintentionally or against the speaker's better judgment.
