If you want to annoy a jealous person, go ahead, and interact with all of his or her best friends.
For instance, if your neighbour is jealous of your brand-new car, park the car in his or her parking spot when he or she is not around.
The least you can do to annoy a jealous person is by getting an attitude towards him or her.
Do you have a picture with a person who is jealous of you? If yes, then here is your cue. Take that picture and crop that jealous person out and then post it on all your social media handles.
When any organizations ask for your phone number, give them the number of that person, who is envious of you.
