well I don't know lot of Nepali people, I don't like going to Nepali parties but due to some of my friends, I went to a Nepali party once, and they really act strange and that they're from completely different planet, they don't welcome you or say hi or introduce themselves to you, i mean, parties are meant for introducing each other and having fun together! but I really don't know if Nepalis are selfish? I think it depends on people.
