New Phrase: てんし (天使) & あくてんし (悪天使)
Meaning and Thoughts: Maybe these words aren't common at all, but I ran across them and thought that I should let everyone know that てんし means "angel" and あくてんし means "evil angel" (not devil?) and apparently it can change in predictable ways too, like for example 大天使 is "arch angel" or something. woo!
