The general style of the song is an upbeat hip-hop backing combined with the soulful vocals of Tulisa and the intensive rapping of Dappy forming an original British hip-hop grime[citation needed] track which's style is reflected in the forthcoming album tracks and singles that appeared on N-Dubz's debut album "Uncle B".

The song, through its lyrics, tells a story about how a man discovers that after his girlfriend starts regularly giving him the cold shoulder that she's in fact cheating on him.

The story of the lyrics goes on into an argument between the couple and the girlfriend admits that she didn't go chillin' with her girl-friends but did, as accused cheat on him.

A perfect mix of rap and vocals mean you don't get bored of it and it tells a great story of infidelity.
