What term describes the act of engaging in a playful flirtation?

The term that describes the act of engaging in a playful flirtation is "dalliance." Dalliance typically refers to a casual romantic or sexual relationship or the act of flirting in a light-hearted and non-serious manner. It conveys a sense of temporary involvement or playfulness, emphasizing the whimsical nature of the interaction rather than a serious commitment.

In contrast, the other terms do not capture this essence of playful flirtation. Dawdle refers to wasting time or moving slowly, lacking any romantic connotation. Cursion does not have a recognized meaning in relation to flirtation or relationships. Debauch typically implies excessive indulgence in sensual pleasures, often with negative connotations, and is not associated with the light-heartedness typical of dalliance. Hence, "dalliance" stands out as the most fitting choice for playful flirtation.
