“Never use a metaphor, simile, or other figure of speech which you are used to seeing in print”.
“Never use a long word where a short one will do”.
“If it is possible to cut a word out, always cut it out”.
“Never use the passive voice where you can use the active”.
“Never use a foreign phrase, a scientific word, or a jargon word if you can think of an everyday English equivalent”.
“Break any of these rules sooner than say anything outright barbarous”.

What a dude! DUDE!
