Since this word consists of a kanji with hiragana attached, you can bet that it will use the kun'yomi reading. You didn't learn that reading with this kanji, so here's a mnemonic to help you:

"Wow! You have a bruise above your eye." "Yeah, I disobeyed my mom last night and I got the shit kicked out of me."
