Old-school nickname for a police officer. It’s tied to Sir Robert Peel, who set up the Metropolitan Police in 1829, so bobbies and peelers stuck. These days it sounds a bit noddy and nostalgic, like something your grandad says, but you’ll still hear it when people are being cheeky or trying to soften the vibe.
"Two bobbies were outside the station having a natter, so I told Kev to hide his Tesco meal deal before they clocked us."
