One who is not a "soydev" (see the definition of soydev on urban dictionary). Can be used the same way that "soydev" is used, except it is negating the conventional definition. For example, one who is a stereotypical programmer who consumes apple products and using a bloated IDE would be considered a soydev by many people. However, someone who commonly uses Linux and edits their code using vim would be considered a soydev'nt in this case, because they are *not* a soydev.
Person 1: "Stop coding on a MacBook, you soydev!"
Person 2: "Why? Your a soydev too!"
Person 1: "No, I am a soydev'nt."
