An idea you have while high that is amazing, even world-changing, that you promptly forget because of your state of highness
Dude, I had such a great highdea last night and I forgot to write it down!

An idea/inovation inspired and construed by an individual who is in an altered state of mind. Later examination revelals that the idea was not so great.
Last night while sitting around the bong with my friends I came up with this awesome HIGHDEA to make a floating phone so they cannot fall and break. The next day I realized that things can't float in real life.
