look up any word, like demisexual:
Boring people who've taken a few months out to go travel the world and come back telling everone how great it is and how their life has changed forever.
A travangelist might be overheard at a humous party saying: "what a good way to gain perspective, money's not as important as it was, etc. etc".

"Did you camp there? Oh, you should have gone to this other spot, it's so much better!"
