'Ad nauseam' is a Latin phrase meaning to do something repeatedly over time so that it becomes boring or irritating: "My life at the moment is just study, work, repeat ad nauseam." "These marketing campaigns are all the same - the same characters, the same close-up shots of the product ad nauseam. We need something radically different." This is an expression used in social and professional contexts but might be more common in formal conversations.
