I think the song is about two friends, or possibly two people in a relationship, who are slowly drifting apart ("This is what the summer became/Only strangers walking down from the beach" ; "Waiting for a bus from this place/And when I get there, I'll just fold up my map/Drop it and never look back") because one of them is basically just being a killjoy/downer/buzzkill. as the song goes on they get more and more hostile towards each other ("treat me like I'm stone/Push me to the back and moan" ; "pulling out my hair/Smash out all the lights, kicking out my chair"). at the end i would interpret it as the one who isnt a buzzkill trying to make up/apologize but it doesnt go well ("Fun assassin, take off your disguise/Look me in the eye and lie").
