Human combination of positions, which takes place between two people (in which one leads to “minechickpeas” the other) by placing the legs astride the neck or even the whole bust on the shoulders (as if it were a backpack).
It usually occurs when someone is unable to walk, or at least very tired.
It is done with children (often), also to allow them a view from a higher position.
In short, a word that expresses mutual solidarity, and all the beauty of helping each other. Nobody knows exactly where it comes from (why on earth should we mine a legume to be carried on our shoulders?), But this time we keep it that way, without investigating further, in all its effective poetry…
