Vivatim

(noun) A narcotic vitamin

Most commonly used when one is referring to a drug as a vitamin in order to be lowkey about it, but the drug has already had it's effect on the person speaking, so it comes out as "vivatim"

As in;
"You should probably consider switching to edible vivatims due to the nature of your nasal injury"

or also

"Yo pass me the bag of vivatims I'm about to kick it up another notch"
