Англичане, хэлп. Что означает выражение "to get high"? I have no idea...

Одна песня, которая мне нравится, называется "He gets high". Смысл самой песни примерно понятен, но что означает конкретно это выражение?
http://www.youtube.com/watch?v=dWHH1jivrxk - вот сама песня. Вот текст:
The man walks down from the 99,
He's got holes in his pockets, he's got too much style,
He's going down, down to town,
Just to meet some pals and to get a bit high,

Going back by the 79,
So much things on his troubled mind,
He is full of whiskey and beer,
And soda and wine.

So he gets high, so he gets high,
So he gets high tonight,
*And so he gets high, so he gets high,
And so he gets high tonight.

He's not everybody he thinks he's the one,
Sitting on the pavement out of time,

*And* he won't listen to all those swines,
He'll break his bottle and fight,

The man walks down from the 99,
He's got holes in his pockets, he's got too much style,
He's going down, down to town,
Just to meet some pals and to get a bit high,

So he gets high so he gets high,
So he gets high tonight,

He's got dream in right eye,
And hope in the left one,
You have a lover for tonight,
He's got music 'til he dies
