{sarcasm} 

syntax used in emails, forums and instant messaging to indicate the start of a sarcastic tone thereby eliminating confussion for the reader. this should be used in conjunction with the {/sarcasm} operator to show the conclusion of the sarcasm.

the same style should be applied to other speech patterns when meaning can not be derived from text alone. other examples include {ball busting} or {grumble}.

NOTE: the prefered square brackets should be used whenever possible

Sometimes added on the end of a written statement that is meant to be sarcastic, especially online. Sarcastic text can often be misunderstood since the reader cannot find an inflection or other indications of sarcasm.

Variants include -Sarcasm-, ~Sarcasm~, =Sarcasm=, <Sarcasm>, etc.

Sarcasm Man 

A superhero that tends to appear when not formally summoned to the scene. His superpower? I don't think you can figure it out...*sarcasm*

He can be dismissed with a sarcastic counter-attack, such as acknowledging his presence.

Thanks Sarcasm Man! I don't remember calling for you, but I'm *so* glad you showed up.
