What does I'm just getting off my face mean?

See a translation

@Andrewhma oh.. I see.. it is lyric of song 12:45 - Etham

@Andrewhma It's 12.45 on a Tuesday and I don't really care what you say
I'm just getting off my face tonight
Cause I'm just tryna live to the weekend
And I don't know how I'm supposed to breathe when
Everything you say is playing on my mind
You don't know where I've been and you don't know what I'm drinking
I need a moment to think about nothing at all
Oh baby you gotta stop I see that you're calling
I told you that I ain't picking up
I know that you wanna start
Cause we got our problems
I love you but I just need tonight off
It's getting pretty deep in the AM
And I should go home but I'm staying
I'll be sleeping on the cold floor tonight
Ohohohoh
I hope you'll understand in the morning
That this is just my problem that I'm solving
Yeah I got a lot of stuff on my mind
I don't know where I've been and what the hell am I drinking?
And I can't help but to think yeah it's all my fault
Oh baby you gotta stop I see that you're calling
I told you that I ain't picking up

@juhisaha oh thank you! Do people say this word commonly?

@Andrewhma Thank you!!!
