It's pretty simple. After this tweet by Dan Barker got thousands of retweets...
Russell Brand's writing feels like someone is about to shout "PARKLIFE!" at the end of every sentence.
...this became a thing.


And so on.

It's beginning to spread beyond Twitter.

Barker, the guy who started the meme, told BuzzFeed News:
Just as Craig David eventually found peace with his Bo Selecta taunters, I hope Russell Brand can eventually forgive me, along with Damon Albarn, Phil Daniels, and @paperclipracket, who pointed out he'd made the observation before I did (his was funnier too).
Explanation for confused American readers: Basically, people in Britain have realised that Russell Brand sounds exactly like Phil Daniels in Blur's 1994 hit "Parklife".
Now everyone's making mashups because that's the internet.
