请问《catch my disease》中的catch my disease是什么意思
这是歌词
Catch my disease---Ben Lee
My head is a box full with nothing
and that's the way I like it
My garden's a secret compartment
and that's the way I like it
and that's the way I like it
Your body's a dream that turns violent
and that's the way I like it
and that's the way I like it
The winter is long in the city
and that's the way I like it
So please
baby please
Open your heart
Catch my disease
I was backstage in Pomona
and that's the way I like it
She drank beer with coca-cola
and that's the way I like it
and that's the way I like it
She told me about the winds from Santa Anna
and that's the way I like it
and that's the way I like it
She told me she loved me like fireworks
and that's the way I like it
So please
baby please
Open your eyes
Catch my disease
So please (PLEASE!)
baby please
Come on
Catch my disease
Catch it
Na na na na na na na na na
They play Good Charlotte on the radio
and that's the way I like it
They play Sleepy Jackson on the radio
and that's the way I like it
and that's the way I like it
I hear Beyonce on the radio
and that's the way I like it
cos that's the way I like it
and they play me on the radio (whoo!)
and that's the way I like it
So please
baby please
Open your heart
and catch my disease
So please
baby please
Come on
Catch my disease
(catch my disease)
nanananananananana
(catch my disease)
nanananananananana
(catch my disease)
nanananananananana
(catch my disease)

情歌里面的disease,可以理解成相思病.
不好直译,意会一下吧,就是向恋人表示自己相思的痛苦,比如"My head is a box full with nothing",可以理解为 我的脑袋里什么都思考不了.
这段大概就是说:
宝贝,请你敞开心扉,请你在意我的相思病.(直译很生硬啊...自己理解吧:))
(baby please / Open your heart / Catch my disease )
