your ass is grass and i'm the lawn mower 

The expression of which your ass is grass comes from if you hear this you better get out of town because you're likely to get shot hung or end up with your head on a stick

Idiot1: oh dude I am so dead
Idiot2: yep that's quite a bit of a fender bender there
- idiot1 gets home-
Idiot1's roommate: heard you my moped just want you to know ass is grass and I'm the lawn mower
Idiot1:* shit himself*

And that my assholes is how the term:
Your ass is grass and I'm the lawn mower
Turned into: your ass is grass

the grass in you front lawn 

The vigina hairs of a woman
Also a way to make fun of slutty Mexicans

the grass in you front lawn is so nice

Jesus you spend more time mowing her lawn than all your jobs combined

lawn gassed day

an expression of relief that a long, exhausting day that can be said in a setting where "long ass day" might not be appropriate.

I hate today was a lawn gassed day.

I hate that was a lawn gassed road trip.

I hate that was a lawn gassed recital.
