It is the pose of a person who is frustrated or angry like "damn it" and slams his arm against the wall.
I wondered if it could be used for poses where you feel sick and lean against the wall, or poses where you are injured and can barely stand against the wall.
「くそっ」みたいに悔しがったり怒ったりして、壁に腕を叩きつける人のポーズです。
気分が悪くなりフラついて壁に寄りかかるポーズや、負傷して壁伝いに立つのがやっとというポーズにも使えるかと。
