what does karma balance mean on profile?

[Elite_Fry]

when you get those grey boxes which to my understand means karma balance...
but wtf does it mean?
i dont want this grey shit i want green shit

 

[rickcorso]

if you get some grey, i think it means that the person who gave it to you doesnt have enough green karma themselves to give green karma to others.
