Once a good level of comfort is established it is important not to let things get too cozy. Pure comfort that is never spiced up with any kind of conflict is warm but unexciting and ultimately leads to a platonic friendship, not attraction. Most people know what it’s like to really like someone who only ever saw them as a friend, and the fact that they never broke rapport is one of the biggest reasons why this happens.

Breaking rapport jars the established comfort with a mild element of conflict or danger. Breaking rapport is exciting! Vocalising a disagreement, teasing or being sexually suggestive are all great ways to break rapport and you should do it as soon as it is safe to do so; when the conversation is flowing naturally and they’re not looking for an excuse to leave, it’s time to break the rapport. There’s no “best way” to do this, but the different choices can help develop the situation in different ways, for example a lewd rapport break (innuendo) paves the way for things to develop sexually sooner.

Why is it important to build comfort first? Well let’s take the following example. If you where to tell someone you had never met that they smell like a sweaty tramp, they are not likely to receive you in a particularly welcome way. However, after a good few minutes of conversation if you where to drop in that line with a smile and a playful nudge, you would be likely to receive a small push, slap or at the very least a slightly warm but shocked look. Smiling is naturally a key point during this, to ensure you maintain a level of comfort and don't ruin what you have already established.

Playing childish tricks such as pointing your finger at someone's chest and making them look before flicking their nose is another good way of breaking rapport, any possible way to tease someone, calling them a geek, tripping them up and catching them. Anything that enables you and them to laugh at their expense will suffice as a tool to break rapport.

Bear in mind that the goal is just to jar the comfort you have already and to make them view you in a different light, not to eradicate the comfort completely. Too hard a break could make someone very uncomfortable and then you’d be right back to square one and have to start rebuilding comfort all over again. For example, “You know, you’re really sexy when you smile like that” is often a fairly safe sexual break whereas “I want to take you home and screw you hard” would make most people very uncomfortable at this stage! Sex is such a taboo subject that any mention of it often serves to break rapport.
