Taking psilocybe mushrooms and MDMA (ecstacy) together. Actually regarded quite highly within the drug subculture. The effects rarely last longer than 8 hours. The effects of the MDMA lend a very upbeat feeling to the user, usually resulting in a positive mushroom trip. Because MDMA is a fairly "reliable" good high, but mushrooms aren't (there can be bad trips), the MDMA high helps to stabablize the mushroom trip.

To ingest both ecstasy and psychedelic mushrooms. Candy flipping is mixing LSD and ecstasy. Although some might think hippie flipping is combining LSD and mushrooms, this is incorrect. There might be some areas where people define it this way, but the VAST majority of people define hippie flipping as combining ecstasy and mushrooms. It's drug slang, so majority rules. Google it and you will find this to be 100% true. Trust Erowid, Shroomery, BlueLight, Mycotopia, etc over one person on Urban Dictionary.
Did you guys hippie flip last night?

We made shroom tea and followed it by plugging a liquid solution of two e pills. I've never laughed so hard in my entire life.

Combining mushrooms and ecstasy. In the early 2000s it was also known as an mx missile, for mushrooms and ecstasy. Back then ecstasy was ecstasy, which is now referred to as Molly by younger people in the 2010s.

When a person mixes Mush With Extacy two of my favourite drugs personally this is a intense mixture. Visuals are intensified, hysteric laughing is a guarntee.
