A cute name/nickname given to a girl who is quite a troublemaker but it's almost impossible to stay angry or annoyed with them for long due to them being so incredibly cute.
Girl: (on Chat) I just gave you 400 notifications on your Facebook account! Ha :D
Boy: Thats annoying but real cute :P
Girl: Yeah. I'm such an Aliena :)
Belief that all Gods of all religions were visitors from other planets. They were more advanced and had technology that the humans couldn't understand so they were perceived to be Gods. Some of the visitors were kind to us and some only wanted to dominate us.
Alientology is a belief that many have and don't have a name for it, they have a solid belief in alien life.
