look up any word, like fleek:
n. A collector of cold nests.

Earlier meanings include 'a person more interested in the past than present or future.'
Here it applies specifically to those nostalgic and obsessed over past shags. Compare the phrase 'A night on the nest' for a one-night-stand!

Jim's a real, boring preterist, always boasting about his past conquests. Keeps a little black book, I'm told.
