It's about people coming outside while you're working on their lawn and critiquing your work.
Lyrics
You cut them low and they're gona die in vain,
If the account catches you they'll go insane,
They'll come outside and they'll bitch,
Piss me off until my eyeballs twitch,
"You cut them too low"
Fuck you asshole you don't cut lawns for a living!
