this is the safe for work term to be used for "Hand job." The number 8 represents the letter "H" because it is the 8th letter in the alphabet and then "J" represent the word "Job" Put the two together and you have hand job. Many use this term to safely talk about sexual favors in public.
I was in the restroom when this chick came in and gave me the best 8J of my life.
