[Verse 1]
I think I'm done with twenty-one, this isn't that much fun
I made a bunch of friends so I can use them as excuses to get drunk
Don't feel like I'm enough
I bought a bunch of shit that doesn't fit but I can't wait to take it off
I cleaned my room, I paid my dues
I did all of the things that they all told me to
I filled my head with common sense
I did all of the things that everybody said

[Chorus]
So how come all the worst days are in the time of my life, time of my life, time of my life?
Yeah baby it's my birthday but I still wanna die, time of my life

[Verse 2]
I think I'm done falling in love, the last one left me numb
I go to all the parties but I really only came here for the drugs
Threw out my fake ID
Been staring at the mirror for a year but that girl still don't seem like me
I cleaned my room, I paid my dues
I did all of the things that they all told me to

[Chorus]
So how come all the worst days are in the time of my life, time of my life, time of my life?
Yeah baby it's my birthday but I still wanna die, time of my life, time of my life
[Post-Chorus]
If this is it I want my money back
Don't make it last, I'm anxious and I can't relax
Yeah how come all the worst days are in the time of my life, time of my life?

[Bridge]
Guess I'm gonna fake it
'Cause I still look amazing, yeah
I think I'm gonna waste this
Time of my life, time of my life, time of my life

[Hook]
If this is It I want my money back
Don't make it last, I'm anxious and I can't relax
Yeah how come all the worst days are in the time of my life, time of my life?
