What is "mucky pup"

n. (context British colloquial English) A typically messy or dirty child or (humorously) adult.

Mucky Pup began as an American hardcore and crossover thrash band formed in Bergenfield, New Jersey in 1986, when brothers John (drums) and Chris (vocals) Milnes joined up with Dan Nastasi (guitar) and former Hades member, Scott LePage (bass). The band went through various incarnations and several musical style changes while gaining minor success in both the USA and Europe. Arguably, their breakthrough moment occurred when Berke Breathed picked their songwriting contest entry for release with a 1987 Bloom County comic strip compilation. However, their European success, based on strong tours and charting for the 1989 A Boy in a Man's World album, surpassed all recognition achieved in their home country. Since reuniting in 2009, the band has featured a rotating lineup of former and new members with vocalist Chris Milnes being the only constant.
