The attack itself is to some point very self explanatory, this is also one of the reason why we have never seen luffy use armament along with gear second until this point, The attack itself is explain by luffys gear seconds power of compression and acceleration due to his rubber body, and alongside Busoshoku Haki, the pressure created from the process of Vulcanization (the process of hardening rubber to a polymer-like material use on bowling balls) and the compression of luffy's gear second and the creates enormous amounts of energy from friction and momentum generated in a molecular scale which causes a explosion on impact (release), this works much like the solar flares we experience from the sun when the energy is compress to such a extent that at the moment of release it generates a momentous amounts of energy causing an explosion (although in a much smaller scale), this is somewhat like the compress air bomb that kuma is known for.
