उत्स्रक्ष्ये मूढ चिह्नानि यैस्त्वमेवं विकत्थसे ॥ ८ ॥
utsrakṣye mūḍha cihnāni
yais tvam evaṁ vikatthase
The Personality of Godhead, after enjoying the jokes of the assembly, told the messenger [to relay a message to his master:] “You fool, I will indeed let loose the weapons you boast of in this way.
The Sanskrit word utsrakṣye means “I will hurl, throw, let loose, abandon, etc.” Foolish Pauṇḍraka demanded that Lord Kṛṣṇa give up His powerful weapons, such as the disc and the club, and here the Lord replies, utsrakṣye mūḍha cihnāni: “Yes, fool, I will indeed let loose these weapons when we meet on the battlefield.”
In Kṛṣṇa, the Supreme Personality of Godhead, Śrīla Prabhupāda nicely describes this scene as follows: “When all the members of the royal assembly, including King Ugrasena, heard this message sent by Pauṇḍraka, they laughed very loudly for a considerable time. After enjoying the loud laughter of all the members of the assembly, Kṛṣṇa replied to the messenger as follows: ‘O messenger of Pauṇḍraka, you may carry My message to your master. He is a foolish rascal. I directly call him a rascal, and I refuse to follow his instructions. I shall never give up the symbols of Vāsudeva, especially My disc. I shall use this disc to kill not only King Pauṇḍraka but all his followers also. I shall destroy this Pauṇḍraka and his foolish associates, who merely constitute a society of cheaters and the cheated.’”
