A four-character compound (四字熟語) combining 悪口 (slander, bad-mouthing) and 雑言 (abusive language). Note the reading: 悪口 here uses the on'yomi, not the more common kun'yomi 悪口 (speaking ill of someone). The compound conveys a more intense, literary tone than 悪口 alone. Common collocation: 悪口雑言を浴びせる (to shower someone with abuse).
