What is yellow heart on snapchat with crush?

As an AI language model, I don't have personal experiences or emotions so I can't provide information about Snapchat feature in terms of experiencing it with a 'crush'. However, here's general information about the yellow heart on Snapchat:

The yellow heart on Snapchat signifies that you are best friends on the platform. This means that you regularly snap each other and have been consistently interacting on Snapchat. It does not specifically indicate that the friendship is romantic in nature, but it could potentially imply a deeper connection with the person. If you are interested in pursuing a romantic relationship with someone on Snapchat, it is important to communicate openly and honestly with them outside of the app as well.
