Humanitourism: The new wave in philanthropy that lets you see the world and help make it a better place.
Portmanteau is basically a word that is two words spliced together that either end up being funny or helpful in some way.
If by ‘new wave’ they mean people that are rich and ‘suddenly feel bad’ about taking ‘extravagant’ vacations given the shitty economy and need a better excuse, then yeah, sure–humanitourism. Missionaries have been doing this and getting killed for years. Have fun.
