مِغْشَمٌ

One who goes at random, heedlessly, or in a headlong manner, without consideration, whom nothing will turn from that which he desires, (S, K,) by reason of his courage; (S;) as also ↓ غَشَمْشَمٌ: (S, K:) or, according to Aboo-Riyásh, one who performs affairs [in a random manner,] confusedly, without discrimination: or, as some say, one who, when the road is unapparent to him, goes at random, without direction and without knowledge. (Ham p. 37.)
