means A police vehicle used to transport people who've been arrested, especially in groups.

from Most likely tied to 'Paddy,' a slang shorthand for 'Patrick' used as a derogatory catch-all for Irish men in 19th-century America, during a period when Irish immigrants were stereotyped as drunk, brawling, or criminal — and disproportionately arrested by city police. The slur stuck to the vehicle. A softer, unproven theory claims it referenced the many Irish cops who drove the wagons, but that account is generally treated as a later, kinder gloss rather than the documented root.
