A British insult for someone you think is worthless, dishonest, or has behaved badly — a small-time cheat, an annoying child, a person who let you down. It is genuinely rude, but it is a mild kind of rude: closer to 'you little rat' than to real swearing. You can say it to a child who has broken something without it being shocking. It sounds distinctly British, and rather dated. You will hear it from older people, in older films, and in stories about the East End of London, more than from young people today. Americans mostly do not use it and may not know it. Sometimes it is written 'toe-rag' or 'toe rag'. There is a real story behind the word, and it is worth telling: a toe rag was once a strip of cloth that a poor person, a prisoner, or a tramp wrapped around their feet because they had no socks. To call someone a toerag was to say they were the lowest sort of person, one who wrapped rags round their feet. The insult has softened a lot since then. Because it is informal, regional, and old-fashioned, it is a word to understand rather than to use — if a learner says it, it can land strangely.

混蛋、渾球、爛人（英式罵人的話，語氣不算很重，比較像「你這個小混帳」）。台灣沒有完全對應的詞，看場合可以是「臭小子」（罵小孩）或「爛咖」（罵不可靠的人）。這是英國用語，而且偏老派。
