birthday sex是什么意思?

google了一下,是有一首歌叫Birthday sex。其实没什么特别的意思，就是顾名思义，在生日那天做爱。

歌词如下：

Jeremih - Birthday Sex

Verse 1
It's yo birthday, so I know you want to ride out
Even if we only go to my house
Sip mo-eezy as we sit upon my couch
Feels good, but I know you want to cry out
You say u want passion, I think you found it
Get ready for action, don't be astounded
We switching positions, you feel surrounded
Tell me where you want your gift, girl

Chorus
Girl you know I-I-I, Girl you know I-I-I
I been feenin
Wake up in the late night
Been dreamin about your loving, girl
Girl you know I-I-I, Girl you know I-I-I
Don't need candles and cake
Just need your body to make...
Birthday sex... Birthday sex oohoohoohooh
(It's the best day of the year girl)
Birthday sex... Birthday sex oohoohoohooh
(G-spot g-spot let me hit that g-spot g-spot girl)

Verse 2
