ID10T

What does ID10T mean?

ID10T equals Idiot

ID10T is a coded way of saying “idiot” using leetspeak, a language where numbers and symbols replace letters. Variations of this term include ID 10 T, ID Ten T, or 1D10T, all designed to be a cryptic way of calling someone an idiot.

The term is often used when someone makes a mistake that’s quite obvious, typically in a tech-related context. If you’re having an issue with your computer and you reach out to the IT department, you might hear them say you’ve encountered an “ID 10 T error.” In this case, the problem is not with the machine but rather with the user. Basically, they’re telling you that you’re the “idiot,” not the computer.

This term is also used in the military, especially when teasing new members. A novice might be asked to fetch an “ID10T form” as part of their initiation process. The pronunciation differs between the Navy and the Army. The Navy pronounces it as “eye dee ten tango” while the Army says it as “one delta ten tango.”
