A very generic and mainstream band from London, UK, who are definitely not, as somebody suggested, a grime crew. They make typical UK pop music. The members are Dappy, who is an idiot who watches In The Night Garden, Fazer, who could have been a credible MC had he not joined N-Dubz, and Tulisa, who is fairly pretty but decided to appear on the X Factor, a rubbish singing-contest which is popular in the UK. Teenagers who follow the crowd listen to N-Dubz; people who like real music definitely don't.
Person 1: "N-Dubz are the sickest grimers"
Person 2: "They aren't a grime crew, and there is no such thing as a grimer"
