Ignoring someone via the internet; giving a virtual cold shoulder. Giving someone the cold keyboard may be due to:
- Annoyance with said person, caused by either a genuine problem or something utterly fucking stupid, like trolling.
- Having gotten pwned and having no possibility of coming back, giving the cold keyboardee immense satisfaction.
Et cetera.
When Johnny didn't understand that Betty's monosyllabic responses to his IMs meant she didn't feel like talking, she resorted to giving him the cold keyboard.
Sally gave me the cold keyboard after I kicked her in the ass arguing logic on facebook. There is no sweeter satisfaction.
