Someone who is literally in love with themselves. They will try to catch a glance of themselves in mirrors when nobody is looking. When caught, they will say they are looking at their hair, a spot etc. They sometimes kiss mirrors, and in extreme cases, fap to their own picture. The vast majority of Egophiles are Egotists.
A combination of the prefix "exo", derived from the word extraterrestrial, and the suffix "phile", meaning "to have an affinity for".
An exophile is someone who has an interest in extraterrestrial life forms, either in fictional material (movies, television, books, etc) or the real possibility of such beings existing somewhere in the universe.
This comes from the Happy Rhodes album "Ecto". Back in 1991, there was a mailing list sent out to discuss her music, and it was also called Ecto. However, the fans who got this mailing list also wanted to discuss other music they liked, and thus, became ectophiles.
