You Are 45% British
You're about as British as a half hearted Anglophile... in other words, a piss poor Brit.
If you are indeed from Britain, you probably consider yourself a European more than anything else.
If you're trying to pass for a Brit, you're going to have to try a little harder.
Go to a football match. Drink until you puke. And head in to work the next morning totally hungover.
How British Are You? My Anglophilia is limited to britpop and the occasional Newcastle ale.
