Deeto

"Deeto" or "Deeting" is inspired by the Pokemon Ditto, who has the ability to take form of another pokemon. This term refers to people who pretend to be in a similar profession or field of expertise so that they can either add value to their argument or win an argument. Used mostly online where the true nature/background of a person is hidden.

Pretender: I know what I'm talking about, I have been programming for 10 years..
Guy 2: No you're just a deeto.
Guy 3: This guy is just deeting stuff lmao.
