Sisterface 

an endearment said to a sister who you aren't very close to, but pretend you are. Whose your relationship is mostly based off infrequent long distance phone calls and interactions. Mostly you keep in touch over facebook. Pretty much not being a person anymore just a face. Hence Sister-Face

Sister 1: Hey sisterface, I saw heard good charlotte pop up on pandora made me think of you, miss you!

Sister 2: Aweee miss you too sisterface! Hope everything is going good!

*Thinking wow haven't listened to good charlotte since I was like 14 I'm 20 now, nice how much she pays attention*
