Macho-Macho is an elixir. It can be bought at Slurps and Burps. Dex uses it in Neverseen in order to disguise himself while the Keeper Crew were outlaws allied with the Black Swan. Earlier in Neverseen, Dex commented that Coiffe (Timkin's bizarre disguise in the Black Swan) most likely used this elixir in order to create this disguise. He deduced that the disguise was created through the use of a lot of the Macho-Macho elixir, a few drops of the Body Warmer elixir, and some of the Curly-Dew elixir. All of these elixirs are familiar to Dex, and are presumably sold at Slurps and Burps as well.
