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.
