Synecdoche, explained

He sediment a topiary
Tried alluviated, vary
Islip agent, Cyprus flu
No friend me – benighted too
Nicked the center, pressed aboard
Canned to go and in accord
Wended frame deliberant
All as many ready spent
Novel sand, or so we go
Frighted may as maybe so
Try to home despairing how
Crisp the sniper, catch the cow
    None descend as freight is why
    Bar as later said, now die

 

Or at least, that was my impression of Charlie Kaufman’s fun new movie. I hope this makes everything clear.
