Getting or receiving fellatio whilst riding in a golf cart.
Hemant was so excited that Kris got a hole in one that he gave Kris grass head in the golf cart.

Get the Grass head mug.
Adj. A person who obsesses over the health of their grass. They spend 110% of their time and money using fertilizers, watering their lawns, and keeping weeds away while treating their lawns like Newborn Babies. They hate dry patches and dog crap. Often you will see them with sprinklers constantly on, shooing people from the grass. After years, one may develop the rare Grass Brain Disease.
Oh my gosh! Mr. Smite is watering his lawn AGAIN! Just another Grass Head on Ray Drive!

Get the Grass Head mug.
Something spectacularly silly and sublimely expressive of the comical futility of human existence. Like a four headed baby conceived between a couple who couldn't even recognise one another because the grass was too tall (or they had smoked too much of it). An utter disaster.
Little Downs-Syndrome Pepita here is Marcia's little four headed grass accident.

His thirtieth birthday party was a four headed grass accident.
