When you cum during a solo ejaculation session, and grab the kleenex you had ready on the computer desk to 'catch' the jizz into the kleenex and then you try to wrap it up while also wiping the tip and during this process of wrapping it up the bubble of jizz and kleenex bursts, THAT is what jizzplosions is.
