To intrude on something generally means to encroach upon or disrupt an area, space, or situation without permission or invitation. It implies an unwelcome presence or interference that disturbs the normal functioning or privacy of the subject being intruded upon. This could manifest in various forms such as physically entering a space where one is not welcome, imposing oneself into a conversation or situation without invitation, or violating boundaries or personal space. Intruding on something typically suggests a lack of respect for boundaries or a disregard for the autonomy or preferences of others, often leading to discomfort, tension, or conflict.
