A selfie that somehow manages to actually capture the real emotions of the person who took it.
I just saw his soulfie...I can feel how elated he is.
Any image, not limited to selfies, depicting a strong emotion that speaks to your inner self or emotion in that moment.
Look at this meme of a sleepy kitten. It's my soulfie.
A selfie with soul. A selfie that stares into your soul.
That's not just a selfie, it's a soulfie!
