noun pejoration
A jerk or jackass. Coined because of an incident where a person was saying something derogatory about a customer frequenting the same restaurant, but didn’t want to use a potentially offending word and so likened them to a friend of his and his company. She tried to guess what he wanted to say but accidentally said the derogatory word because they knew two people with that name. The second one is an aquarist and now they use that word to make derogatory comments in public without offending passersby.
“He’s such an aquarist”
Etymology : Pejoration of the word aquarist “a person who works with or keeps aquariums”
