Cross-handed, or elbow fist? These are two different things:
Squinting is a physiological characteristic; it is associated with the palmar side of the human body and with the arms. Squinted people tend to have more angled arms than symmetrical people. With such a genetic quality, club-handed people are a strong but clumsy version of a person. But the elbow fist is a kind of gesture used to demonstrate disagreement with the interlocutor. The gesture is common in colloquial speech, and it has a special interpretation: a demonstration of disagreement, a block in resolving a conflict. If a person showed an “elbow” fist or put two fingers aside or stuck them out as a sign of disagreement, then you failed to convince him. Now in a conversation he has either already accepted his position in advance, or really wants to maintain it. This type of communication is called the “goat horn” game; it is with the help of these gestures that subordinates negotiate. They know that they will not find mutual understanding with management if they show them their elbow.
