So seriously: a phrase in the English language meant to convey sarcasm. Spoken in a flat tone after a statement in which the speaker is shocked by the stupidness of the act or statement in which the speaker is commenting on. Not to be confused with, So, seriously, or So-seriously which is separated by a comma or a dash and is a phrase that is actually meant to convey 'actual' seriousness.

Literal Definition: Serious and a Half

Basically, Seriously.5 is an enhancement to a dialogue that is said when the audience is in disbelief at the authenticity of an argument, event that took place etc... The speaker then re-establishes the argument as being Serious.5 which would therefore add extra emphasis to how "real" or "true" the speaker's statement actually is.
