A fist bump is a great way to greet someone, especially if you're looking for an alternative to high-fives or handshakes. Though once considered informal, fist bumps are now commonly used in both casual and business settings as a substitute for the handshake. It's easy to learn the basic fist bump, but there are also many variations you can try to add some fun to your greeting.
Steps
How to Perform a Classic Fist Bump

Make a fist by curling your fingers into your palm. Ensure your fingers are pressed firmly against your palm so your hand is completely clenched. This is the position you’ll hold your hand in when you go for the bump.

Extend your fist in front of you. Hold your fist out in front of your body with your knuckles facing upward. Look at the other person to see if they're ready to reciprocate. If they don't seem to notice your gesture, glance down at your hand to help them realize what's happening.

Gently push your arm forward to meet their knuckles. When the other person raises their fist, move your arm forward so that your knuckles make contact with theirs. Be careful not to do it too forcefully, as it could hurt them or come across as too aggressive.
Trying Out Fist Bump Variations

Twist your wrist at the end for a pocket bump. Perform the normal fist bump, but after your fists meet, rotate your wrist 90 degrees upward to complete a pocket bump. This adds a unique flair and can be a special move you share with a close friend.

Give each other a hip bump after the fist bump. If you're particularly close with someone and regularly do fist bumps, consider adding a hip bump after the gesture to strengthen your bond. Stand side by side and gently bump hips if you're both excited about something.

Open your hand and wiggle your fingers for a fist bump explosion. After you make contact with knuckles, spread your fingers out, pull your hand back, and give your fingers a wiggle. If both of you do it, it will look like an explosion.
Understanding When to Use a Fist Bump

Use a fist bump as a greeting. When meeting someone, a fist bump is a simple and friendly way to say hello and introduce yourself. You can use it in places like the school hallway or when you bump into a friend in a social setting.

Swap handshakes with fist bumps. Think of moments when you'd typically offer a handshake, and instead, try a fist bump. This could be when you're introducing yourself or meeting up with friends. You can even use a fist bump as a way to say goodbye.

Celebrate someone's achievement with a fist bump. Instead of opting for a high-five, why not use a fist bump? The gesture is often tied to sports, where it originated as a way for athletes to celebrate a great play or goal.
