Here are some tips on how to flirt on Snapchat:

1. Send flirty photos and videos. Try sending a photo of you doing something silly or goofy, or send them a hot selfie. Make sure your photos are tasteful and not too racy, or you may end up scaring your crush away.

2. Send a Snap that’s relevant to you and the person you're flirting with, whether it’s an inside joke, a favorite pet, or a song you both love, so you can share something you both enjoy.

3. Capture a flattering selfie by pointing your chin down while holding the camera a little higher than your face.

4. Tease your crush periodically and pepper them with cute selfies and questions to keep their attention.

5. Use Snapchat to your advantage by playing with cute filters and checking in on their story to let them know you’re interested.

6. Move from basic snaps to DM convo to get more intimate and take things to the next level.

7. Ask questions and listen to his responses with genuine attention and interest.
