The word "撩人" is formed by combining the verb "撩", which means to tease, provoke, or stir up, with the noun "人", meaning person or people. This creates a verb-object compound where the action of "撩" acts upon "人", literally translating to "to tease people". In usage, it functions as an adjective describing something or someone that is alluring, captivating, or has a teasing effect on people.
