Lines form on my face and hooves  
Lines form from the ups and downs  
I’m in the middle without any plans  
I’m a filly and I’m a mare
 
I’m eighteen, and I don’t know what I want  
Eighteen, I just don’t know what I want  
Eighteen, I gotta get away  
I gotta trot out of this place  
I’ll go galloping in outer space, oh yeah!
 
I got a foal’s brain and an old mare’s heart took eighteen years to get this far  
Don’t always know what I’m talking about feels like I’m living in the middle of doubt
 
‘Cause I’m eighteen, I get confused every day eighteen, I just don’t know what to say  
Eighteen, I gotta trot away
 
Lines form on my face and my hooves  
Lines form on the left and right  
I’m in the middle, the middle of life  
I’m a filly and I’m a mare
 
I’m eighteen, and I like it  
Yes, I like it  
Oh, I like it! Love it! Like it! Love it!  
Eighteen! Eighteen! Eighteen! Eighteen! And I Like it!
