Critical Grass

1) N-The immeasurable point at which further inhalation of marijuana smoke will no longer get the user more high, and proceeds to only make the user sleepier.
2) N- The immeasurable point at which your lawn mower bag will hold no more grass.

Ex 1. Jimmy is way past critical grass, I bet he's passed out in an hour.
Ex 2. Load another bowl, I'm along way from critical grass.

Long grass, must be long stem and very green, tall enough to hide a pack of hunting velociraptors.

Grass-Button

Grass-Button is a sex position involving four people of any gender combination. It is when there is a chain of four people having intercourse on their knees outside all at the same time. The origin is the grass is because it is outside and the button part is because a button has four holes and four holes are needed for a successful Grass-Button.

Girl: "Hey I feel like having a Grass-Button, any of your friends wanna come join? it has to be multiples of four though!"

Boy: "Of course!! I love a good grass-Button"

Festival Grass

Grass that was once living green lawn, but has succumbed to excessive traffic or heat. If you sit on it you get covered in bits of dead grass. Typically found in Australian backyards during summer, and at music festivals.

Three days of 40 degree heat and my backyard is just festival grass.
