Green corner?

[jonezjollyfarm]

Can someone tell me what the green corner on some of the profile photos is? I thought it was people who are currently online but after looking further I don't think that's right. I searched the help section and searched in the articles and what not. Its been driving me crazy. Sorry If the information is right there but I cant find it.
