The pre-teen act of trying to get high by cramming three large peppermint patties in your mouth, and then drinking a liter of Mountain Drew in one go to wash it down. Also used to describe desperate and often worthless "legal and hidden" ways to get high, like smoking banana peels, eating a lot of nutmeg, etc. Started at science fiction cons in the 1990s, now big among cosplayers and weeaboos.
Guy1: My 11 year old brother was throwing up all night after Mountain Freshing with his gamer pals.
Guy2: He believes that stuff? What ever happened to marker sniffing? Kids today...
Guy1: Best smelling vomit ever, though.
