Someone who is sorted out for E's and Wizz had bought some drugs (most likely ecstasy and speed) in order to have a good night in English club, British pub or UK festival. This sentence is mostly known for being a name for a song by British indie band called the Pulp. Jarvis (guy who wrote tis song) first heard 'Sorted out for E's and Wizz' from his (girl?)friend and he thought that this sentence is genius.
-Mate, can you sort me out for E's and Wizz?
-No, but i have kittens
-Ok. Miaow will do. Cheers.
-Cheers. See you in a bit
Oh, is this the way they say the future's meant to feel?
Or just 20,000 people standing in a field?
And I don't quite understand just what this feeling is
But that's okay cos we're all sorted out for E's and wizz
