To be extremely stoned, to the point of being on at least planet 9. Usually this will require THC combined in multiple forms. To get loogied, I generally will eat an edible, then once it starts to kick in I smoke a blunt and enjoy several hits from a dab cart. You'll know you're loogied when you're loogied because you feel farther out in the galaxy than you've ever been before.
