2. A particular kind of (Western) tourist found in Egypt. They travel in large groups and can be seem performing rituals in pyramids, for which they have religious/supernatural reverence, or nearby temples. These rituals can include humming and chanting, joined palms raised, while standing on one leg.
2. Man, I took some friends out to the pyramids and a circle of pyramidiot tourists scared the crap out of me with their eerie chanting. Why can't they just take photos like normal people?
Person B: "You, sir, are a pyramidiot!"
