The term INTRUDE can be broken down into three words: BARGE, HORN, and BUTT. BARGE is a large boat used for carrying cargo or passengers on inland waterways. HORN is an instrument made of brass or other metal that produces a loud sound when air is blown through it. BUTT is a verb meaning to push or thrust oneself forward without invitation or welcome. Therefore, the term INTRUDE can be defined as pushing or thrusting oneself forward without invitation or welcome, similar to barging in uninvited.
