darb

An old-school American slang gem meaning something — or someone — that's absolutely top-notch, a real treasure. If you call someone a darb, you're saying they're the bee's knees, a total peach. Popular in early 20th-century slang circles, especially in the 1920s. In Australian English it flipped to mean a cigarette, so context matters. Either way, it's a term of enthusiasm and praise for the best of the best.
