An acronym for "Delete If You Don't Know Me". Usually used in sending blanket emails to cover a large number of audiences in global corporations. This term is most likely to be found on those spam emails to say the sender is leaving the company.
e.g. (Alice and Bob both received an email from Charlie with a subject line "Leaving the firm - DIYDKM")
Alice: Have you seen Alice's leaving email, the one with DIYDKM.
Bob: Yes I saw, I can't wait that this first class wanker is finally leaving! Let's go out and have a drink tonight to celebrate!
Alice: Deal!
