Don't be redundant. Don't more use words than necessary. It's highly superfluous. Profanity sucks shit. Be more or less specific.
Understatement is always best.
Exaggeration is a billion times worse than understatement. Analogies in writing are like feathers on a snake. The passive voice is to be avoided. Go around the barn at high noon to avoid colloquialisms. Even if a mixed metaphor sings, it should be derailed.
