Used as a code word over the phone. The person on the other line must guess it however if they do not know you add things to "green cow" such as my green cow space to say the word myspace.
Julie:I dont know she sent my something on green cow.
Mike:What?
Julie: on my green cow space.
Mike: oh, o.k. on your myspace.
Julie: Exactly!

William Green was killed by a Prince Georges County police officer on January 27th 2020. He was shot 6 times close range by Cpl Michael Owen Jr inside of his cruiser while handcuffed and seat belted. 6 shots is a OVER KILL and he should be charged accordingly! #blacklivesmatter. Pg County has a bad history when it comes to police brutality and nothing has been done about.
