Although Josh is infamous for his drink combos and nasty rotting concoctions he affectionately calls 'mead', he has a long and twisted relationship with alcohol. Like a proper toddler, he holds a belief that a real man drinks. Therefore, even if he hates the taste of alcohol, he must drink to prove his worth to the world. Also, it probably helps him cope with depression.
One day, the thirst became so bad that the boy watched some video about mead making, leading him to believe that even he can successfully create mead. Which further lead him onto a path of no return, full of failed biological experiments that would make the Umbrella Corporation blush, making pruno at best, and rotting sugary drink on average, because Jorp simply does not understand that throwing random things into a bottle and letting them ferment won't result in dank mead on it's own.
Since the beginning, he has made over dozen of 'meads', with increasingly horrifying results, no doubt helping his rotting teeth to speed up their demise.
