Alias is an adjective to describe a very stealthy situation or someone wearing all black a la the television series.

Another name that people use to disguise themselves. This can be done anywhere, but is usually online because it is hard to identify someone's true name except through their IP address, which isn't foolproof.

Variations on the word are aliasing, the present tense verb form, and aliaser, referring to the actual person hiding behind their false name, whose identity will never change (in online situations).

Aliasing is frowned upon because people may think that you're a new person, or in small-community games where everybody knows everybody, possibly even cheating. People like to get to know a regular client's personality, and develop a friendship or rivalry with them. Aliasing disrupts this, since you never know if you're talking with friend or foe.
That guy...He must be using an alias.

I think Bob is here, but he's aliasing.

The aliaser is aliasing if he uses an alias.

Incredibly contrived and far-fetched (but still great to watch) TV show starring Jennifer Garner, Victor Garber, Michael Vartan, and Mia Maestro.
