When somebody ignores/pretends you don't exist. Almost as if they're telling you to go fuck yourself, but without actually saying it.
Person 1: Hey there! How are you doing?
Person 2: ...
Person 1: Soo.... what's up?
Person 2: ...
Person 1: Well I guess i'll just go fuck myself, then.
go fuck somewhere else another way to tell someone to fuck off and go fuck themselves at the same time when you are not afraid to use stronger profanity
