Dandere 

Dandere, oftenly confused with kuudere, is a common anime trope used to describe people who are often quiet and extremely shy towards people they like. Despite this, once they do start to conversate (usually awkwardly) with the one they admire, they become more open and less shy.
The reason this is confused with the definition kuudere is because both tropes hardly talk, and occasionally show their more open side. A kuudere is someone who is often emotionless and clueless, but will sometimes show their loving and kind/sympathetic side.

A character that is a dandere: Hinata Hyuga from Naruto.
A character that is a kuudere, not a dandere: Kanade Tachibana from Angel Beats!

dude: "ahahaa, *insert name here* is such a dandere. she hardly talks but she's for some reason really nice and open to me. rarely, though."

dude 2: "man, you are so lucky."

The elderly set of people engaged in the task of getting older. The sheer bulk of Baby Boomers makes it fashionable to be a dodderati. See "doddering"
