Champ (brúitín in Irish) is an Irish dish, made by combining mashed potatoes and chopped scallions ("spring onions") with butter and milk, and optionally, salt and pepper. It is simple and inexpensive to produce. In some areas the dish is also called "poundies."
Champ is similar to another Irish dish, colcannon, which uses kale or cabbage in place of scallions.
The word champ has also been adopted into a popular Hiberno-English phrase, to be "as thick as champ", meaning to be stupid.
