Noun. A reference to the band MGMT and Christmas trees. In order to create an MGMTree, one must take a white artificial Christmas tree, paint it neon colors, use black lights and strobe lights for the lights, and glowsticks for ornaments. One must play either MGMT or other techno music when the tree is turned on.
