Maybe I just have a dirty mind. It's been described as being about wanting to relax and party after working hard but I feel like there is a bit of a double meaning in there...
"Holding on the drinks with both hands tied on them
And I stay on this seat until I have to climb off it
I am approachin’And this world ain’t making me scared no moreWhen Champagne all over myself I pour
One eye keeps turning crossed too far
And talking is so hard when this different side of me does its part
And this world ain’t making me scared no more
When Champagne all over myself I pour"
Maybe it lost something in translation (or gained something)
