You know international fans have embraced making "nugu" into an anti-insult when groups we love, like Craxy, release an album with the title track "Nugudom" ROFL

Fine, it became an insult (apparently?) among K-nets, but at least for Americans we tend to have a soft spot for underdogs. Americans and Europeans also really like rock and jazz, unlike most Koreans, according to recent polls which put those 2 genres at the bottom of the list in terms of Koreans' taste, and I think that's where you also get that disjoin between how groups are viewed at home and abroad.

You can downvote me all you like, I don't give a damn, but I will say this: 

ANYONE who use the word "nugu" to discredit/insult ANY Kpop group or singer, is an idiot and a fake Kpop/Music fan! The fact that people use this word means, they don't know shit about the music industry, and they ONLY interested in overhyped, mainstream singers/groups! Not to mention, they use this word to feel better, especially when a so called "nugu" makes better music and perform better than their faves.
