What kind of figure speech is I been thinking bout you and know do when be them kisses girl so are you?

This is an example of a rhetorical question. A rhetorical question is a question that is asked for effect, rather than for the purpose of getting an answer. It is often used to make a point or to emphasize something. In this case, the rhetorical question is used to emphasize the speaker's desire to know when they will be kissed by the person they are addressing.
