Used to have a boss who we all referred to as Mr Metaphor after meetings....
"Peel back the onion"
"Put that in your job jar"
"If Mohammed can't come to the mountain ...." (pre 911)
But my all-time personal peeve is the use of 'irregardless". It's "regardless" not "IRregardless"!
Even more errant is the phrase, "I could care less."
If they could then why say so?
It should be, "I could NOT care less."
