I know this is really vague, but it's driving me batty.

I'm looking for the artist and song title of a song I heard at American Eagle while shopping. It's a British rapper/hip hop guy. I was told he's white with dark hair. The song was comical. It was about a girl/girls in general. I can't f'ing remember the chorus, but it's stuck in my head. Please help in amy way you can, even if it's just a suggestion.

And I think he had a video in which he was looking at pictues and they kept changing.
