What is unexpected kiss on the cheek from a guy mean?

An unexpected kiss on the cheek from a guy can have various meanings depending on the context, relationship, and cultural background:

1. Friendship: In many cultures, a kiss on the cheek is a common greeting or farewell gesture among friends. If the guy is a friend, it might simply be a platonic expression of friendship or affection.

2. Cultural Norm: In some cultures, kissing on the cheek is a customary way of greeting or showing respect. It might not carry any romantic connotations but rather be a part of social etiquette.

3. Romantic Interest: If the kiss is unexpected and there are other signs of romantic interest (like body language, compliments, or spending more time together), it might indicate that the guy has feelings beyond friendship.

4. Comfort and Support: In situations where someone is upset or in need of comfort, a kiss on the cheek can be a way of offering support and reassurance.

5. Spur of the Moment: Sometimes, actions like these can be spontaneous and not necessarily well-thought-out, without any deeper meaning involved.

6. Flirting: It could be a form of flirting, showing interest in a playful or subtle manner.

To understand the exact meaning, consider your relationship with the person, the context in which it happened, and any other cues you might have noticed in his behavior. If you're uncertain about the intention, it's perfectly okay to ask for clarification.
