A sirius attitude is an attitude in which the person being sirius should not be taken seriously unless it is a serious matter. If it is not a serious matter, it then becomes a sirius matter, in which case one can simply overlook it to save themselves time.

Sirius can be spelled as SIRUS as well.



Sirius may also be used as an adjective, such as a Sirius Shadow (to describe a person), where no one cares about what he says, or a Sirius Noob (to describe someone being overlooked for being bad).
