nobody是used to be

Im gonna drink till I feel pretty
Im gonna laugh till you get mad
Im gonna dance with three more strangers
Till you get over what you had
I can feel you starin at me
And I just love good irony
The only shot you gots one more taquilla
Cause I aint nobodys used to be
Its gettin late
A little lonely
And what youre thinkins all to clear
Lucky for you Ive had too many
Im just drunk enough to leave you here
I can feel you starin at me
And I just love good irony
The only shot you gots one more Jack Daniels
Cause I aint nobodys used to be
You can stop anticipatin
Just go home I know shes waitin
And I know youll be wishin it was me
Honey I aint nobodys used to be
