Ligar in Spanish means “to flirt” and you would refer to someone as a flirt by either calling the person ligón (in the case of a guy) or ligona (in the case of a gal). So, to refer to someone as a flirt would go something like this: Eres un ligón. (“You are a flirt” - for a guy) Eres una ligona (“You are a flirt” - for a gal)
