Refers to da minor-to-medium rocking/shimmying of a single-wheel hand-cart dat occurs when ya momentarily release one of da handles to raise yer hand in greeting to a passerby while trundling said wagon along da roadside.
One fairly easy way to minimize da degree/effects of while-waving wheelbarrow-wobble is to simply brace yer hip against da 'barrow's "free" handle to help hold it stable whenever ya hafta let go of it wif yer hand; wif a little practice, ya may not even need to stop walking, but can just steadily "keep on truckin'" and then re-establish yer grip on da 'barow's handle as soon as ya are able.
