Devnull 

(Verb, Software Engineering related)
To ignore something completely.
Root: In most unix systems there's a device called /dev/null. This device will ignore everything forwarded to it. Likewise when someone "devnull"s something they completely ignore it as it never existed.

Siavash: Sam, ya heard about new Microsoft Windows 8?
Sam: That doesn't even exist yet!
Siavash: Listen to me, it looks great! just try it once.
Sam: are you devnulling me?

/dev/null

/dev/null is a character device file on UNIX computer operating systems that accepts all data written to it, without storing it. It can be opened by many processes simultaneously, and writing to it doesn't cause the file to grow. Formally, it's described as being an infinite data sink. In shell programming, unwanted output from a command can be redirected there. For example:

find / 2>/dev/null

This would display the full paths to all the accessible files on the computer, without displaying the "Permission denied" errors that are likely to occur.

When programs try to read from /dev/null, they get an end-of-file error.

The idea of a null device was imitated by Microsoft in MS-DOS. In DOS, 'NUL' is a reserved filename. When you open a file with that name, DOS opens its equivalent of /dev/null. This behavior was inherited by Windows. In Windows,
even versions of it that are based on the NT kernel, you cannot create a file called "NUL".

It is usually pronounced as "dev null", not "slash dev, slash null." Programmers sometimes refer to /dev/null as a place to send any unwanted information, even if, for example, the data is being transmitted as spoken words from a human's mouth.

"I didn't give a shit about what the Resident was saying, so I simply redirected everything he said to /dev/null."
