The act of suddenly ceasing all communication with someone the subject is dating, but no longer wishes to date. This is done in hopes that the ghostee will just “get the hint” and leave the subject alone, as opposed to the subject simply telling them he/she is no longer interested. Ghosting is not specific to a certain gender and is closely related to the subject’s maturity and communication skills. Many attempt to justify ghosting as a way to cease dating the ghostee without hurting their feelings, but it in fact proves the subject is thinking more of themselves, as ghosting often creates more confusion for the ghostee than if the subject kindly stated how he/she feels.

Common behaviour: Not text you back or ever call you, when the other party does that; they go around saying other party has “ghosted” them.

Not the correct use of the term.

Please don’t do this, you end up looking like a twat.
