"uwu" is not actually a word, but a text emoticon. If you look closely, you can see that the "u"s represent two little closed eyes, and the "w" represents the mouth of some kind of mammal. The resulting expression is intended to and does indeed generate adorability, so the mammal is widely presumed to be a small dog or a cat. This is not to say that it couldn't possibly be a seal or something similarly appealing.

One should exercise caution in using the "uwu" emoticon without clear irony, especially as a male, as it can have negative connotations outside of weeaboo circles.

A weeaboo is a person from a western culture who is obsessed with Japanese culture at a superficial level. Being around this type of person is normally uncomfortable for people from both Japan and the west.

They are characterized by their extensive knowledge of various anime, insistent use of Japanese phrases ("Kawaaii! etc) and unsettling interest in suggestive drawings of girls/childlike women.

Their understanding mostly comes from imported Japanese pop culture seen through the distorting lens of their own experience of social isolation in a western context, and they are not to be confused with people who have a genuine in the culture and history of Japan.

Coming to prevalence in 2016, "mood" is a slang term roughly synonymous with "sentiment", specifically a sentiment that is familiar to the speaker and that he/she recognises as being well expressed.

Person 2: Mood

Derived from the 2000 Eminem song "Stan", a Stan is a partially derogatory term for a fan of a celebrity or a piece of pop culture. Much like the titular character in the song, who kills both himself and wife out of frustration at not receiving a response to his fan letters, it implies a crazed level of admiration or obsession.

The term has been appropriated by "Stans" over time to simply mean a passionate fan. It is particularly popular on social media.

Ex "That dude is such a stan, he drove all the way to Bel Air just to see Beyonce's house"

Ex. "We stan Arianda Grande"

Person 2: You look absolutely fabulous, no cap!
