First, it's a Beatles song. John Lennon is singing it.
He's actually singing "...He was such a stupid git!" In the UK, a "git" is a jerk or jackass. And there was a brand of cigarettes named after Sir Walter Raleigh.
I suspect he was chain-smoking at that time.
Though, if you look into Sir Walter Raleigh's bio, he really WAS a git!
