Your son Duryodhana considered that action of the onlookers to be an insult to nim. Rolling his eyes in anger and as if consuming the Pandavas with his looks and contracting his brow into three furrows and repeatedly biting his nether lip, he addressed the Pandavas with Keshava in their midst, saying-
अवहासं तु तं मत्वा पुत्रो दुर्योधनस्तव। उद्धृत्य नयने क्रुद्धो दिधक्षुरिव पाण्डवान्॥ त्रिशिखां भृकुटीं कृत्वा संदष्टदशनच्छदः। प्रत्युवाच ततस्तान् वै पाण्डवान् सहकेशवान्॥
