DIKY

DIKY stands for “Do I Know You?” It is a question often used online to ask someone if they are familiar with or recognize the person they are speaking to. This internet slang term is commonly used to clarify if the person they are interacting with is someone they have previously met or had an interaction with.

Examples:

1. Person A: Hey, did we meet at the party last night?
  Person B: DIKY? No, I don’t think we’ve met before.

2. Person A: You seem really familiar, have we talked before?
  Person B: DIKY? We haven’t spoken before, but maybe you’ve seen me on social media.
