If you use it in a satirical situation, self derogative way, non-pretentious manner, surreal way, subtetly ...all relatively good.

sarcasm isn't just things like 'yeah, cos we all know how smart you can be..'...you know, the plain and common one used.

Saying all that, it isn't that good to discuss stuff like this. May begins to dull the senses. Let it be...let it flow.
