e-cquaintance
Somebody you know online through text, voice, or video, but would probably not recognize if they walked up to you and said, 'Hey, it’s me.'
'We’ve video chatted twice. I still don’t know what they look like.'
'She’s my e-cquaintance. We talk every day, but I’d probably scream if I saw her in the grocery store.'
'He’s my e-cquaintance. He’s got a dog. I don’t even know what color it is.'
