The leaning position is a spanking position. In this position, the spankee is standing and leans their hands against a sturdy object such as a wall, or the edge of a table. The spankee's legs can be kept together or spread apart. The leaning position is easy to assume, so it's a common position for introducing a bottom to spanking, or for an on-the-spot spanking.
This position is also used for personal search of suspects by the police (see also inspection).
