A good way to make your friend jealous is hanging out with other friends. Many people fear they're missing out, and if your friend sees you making plans with others, he or she may become jealous.  Make sure your friend knows you're hanging out with others. If your friend asks you to hang out on a Saturday night, note that you're hanging out with another group. You can also bring up events that your friend missed when your hanging out with mutual friends. In a group, mention an inside joke you guys formed during a movie night your friend missed. A good way to make others jealous is to find subtle ways to brag about yourself. Outright bragging may feel too awkward for you, so find ways to work small brags into day-to-day conversations.  Talk about your accomplishments in a way that makes you look gracious. When you have success, try to talk about it in a way that conveys excitement. For example, you can try something like, "I can't believe I got an A on that test. I'm so happy and grateful my Mom helped me study." Be a little self-depreciating. You can brag about your achievements while simultaneously downplaying them, allowing you to show off without being too overt. Say you got an internship. You can text something like, "So tired. I just spent all day doing the work the real employees don't want to do." This acknowledges your internship without succumbing to outright bragging. Social media often makes other jealous. As you pick and choose what to share, you can cater your updates to make things look better than they are. You can find ways to make your friend jealous by posting happy statuses and updates on social media accounts.  Post things from vacations and outings. If you had your nails done, for example, post a before/after picture. Update others on your successes via social media. If you got a new job, for example, post about it. If you did great on a test, let others know on Facebook or Twitter. If you're going out with other friends, post pictures and updates. If your friend sees them, he or she may get jealous. Everyone has things that come naturally to them. If you have a particular strength or talent, showing it off can inspire jealousy. If you're a great writer, for example, have your friend read a story you wrote. You can claim to be asking for feedback when you're really showing off.

Summary:
Hang out with other friends. Brag in subtle ways. Use social media to your advantage. Show off your strengths.
