It don't take

 Much thinkin 

Maybe it's

 A mindless robot 

You sick fuckin

 Bitch 

So you sit there

 Stirring while I sit on the toilet slamming the cabinet when I use the bathroom informing the world 

The bathroom

 Got the lowest ceiling 

The vent in there

 Is that how you see me 

Can you see me sitting on the

 Toilet 

Prop you right at the bathroom

 Cabinet 

What is the trade off

 For the cabinet slam 

Again

 I hear you walking around 

So is there a problem with the vent

 Or  a person doing more dumb shit
