请帮忙：get down什么意思？怎麽弄不懂这个词组：get down and move it all around

很明显是后街的歌词么~那个MTV你看了没~老早录的
这句的意思要从全文看的,看完你就知道了~
----原歌词----
Get Down
歌手：backstreet boy

You're the one for me
You're my ecstasy
You're the one I need

Get down
Get down
And move it all around
Hey baby love I need a girl like you
But tell me if you feel it too
I'm in delusion every minute every hour
My heart is crying out for you
I feel in heaven when I look in your eyes
I know that you are the one for me
(One for me)
You drive me crazy cause
You're one of a kind
I want your lovin'
And I want it right now
Ooh baby you're so fine
I'm gonna make you mine
Your lips they taste so sweet

You're the one for me
You're my ectasy
You're the one I need
Bang, bang, bang
Here we come
Here we slam
It's the Fun Factory
with the BSB's
Get on
