e-friends
An e-friend is someone you call a friend even though you only know them from the internet, and they probably think you’re a weirdo.
"He’s my e-friend. He thinks I’m a genius. I think he’s a delusional idiot."
"We’ve been texting for months. I call him my e-friend. He calls me a weirdo."
"She’s my e-friend. We’ve never met. She said I’m the best friend she ever had. I said she’s the worst."
