1.
riding on someone's shoulders; shoulder ride; piggyback on shoulders
Carrying a person (usually a child) on one's shoulders, with their legs hanging down on either side of the carrier's neck. A common sight at festivals, parades, and family outings.
Common patterns
Used with する: 肩車する (to give a shoulder ride) or 肩車をする. The person being carried is not usually the subject — the carrier performs the action.
Usage
肩車 is a warm, nostalgic word associated with childhood memories. It literally combines 肩 (shoulder) and 車 (vehicle), suggesting the shoulders as a kind of vehicle for the child.
