It means he is casual with kissing and what he did with you he will likely do with another girl under the same circumstances. There is alot of context missing in you story so I can only speak to what you shared.
In contrast to his actions, think about the romantic and respectful approach of being asked out on a date and getting to know eachother socially and emotionally. Then maybe under a starlight sky as you two contemplate eachother and gaze into eachtohers eyes and get a sense of connection, maybe you would get that kiss.
But to walk up to you in a bar and kiss you does not show class or respect to you. You are not cheap but he treated you like it.
We learn about ourselves in relationship with others.
