look up any word, like donkey punch:
 
1.
Deadly or dangerous, but enticing, seductive and satisfying at the same time.

À la Beyonce Knowles' "Bootylicious," Necrolicious comes from "Necro-" which means "death" combined with "-licious" which is a psuedo-suffix playing off of the word "Delicious."
These bath salts are NECROLICIOUS.

Let's have a NECROLICIOUS night together.

You're so NECROLICIOUS, my love.
