The act of putting a dorito on a liquor glass filled with Mountain Dew. It is called peasantini because the company that makes the products is paid by Microsoft to heavily advertise the Xbox One (which is an inferior, shitty machine that ruins gaming and is made for peasants) on their Doritos bags and their Mountain Dew bottles. So therefore it is called peasantini, a delight for misinformed people getting the worst possible gaming experience.
