Unarmed fighting is an ADOM weapon skill referring to the act of fighting in melee using parts of the PC's body, instead of using a melee weapon. Bare hands are the most reliable choice of weapon since they cannot be destroyed or disarmed, but for most PCs the higher base damage and other benefits of weapons outweigh the risks. As of v 1.2.0, kicking both trains the unarmed weapon class and benefits from it. In 1.1.1 kicking trains unarmed fighting but does not benefit from it[2]. Unarmed fighting is incompatible with true berserking, which is surprising given the fluff of the beastfighter.
