e-bff - A fake friend who talks to you through the internet, but you

A fake friend who talks to you through the internet, but you’ve never met them, and they probably don’t even like you.

You’re my e-bff, but you called my dog fat.

We’re e-bffs, but you’ve never even seen my dog.

You said you’d be my e-bff forever, but now you’re talking to my dog.
