Or you can choose to be absurdly pedantic at all times. “Jab” is just a conveniently shortened term for your 14-syllable phrase. Many of us can use a term like “jab” when referring to Covid shots informally without thinking for a moment that the shots are harmless or desirable.
I personally think that “jab”, being a British term, is something of an affectation, so I prefer to use “shot” instead.
” so I prefer to use “shot” instead.”
Just go with “poison poke” instead.
