Rants are when users go on about something that irks them, usually ending (the comic ending) in them saying "please stop!" or "calm down!". A rant may have bad results, such as arguments, hatred towards others and misunderstandings.
A typical place for rants is white voids, with no scenery. Sometimes people will put the rant in a scene, but with very little to no detail. Since then rants and any news strips in general are associated with a white void.
