Google works for Orlando Bloom, at least the orignal pre-AW-inside-joke Orlando Bloom. Not sure about Eggplant, but both of these are "required entries" in any poll, for reasons that started up before I got here.
Dunno anything about Gophers, and I've been here a while. Have a thread in mind that maybe I'm missing?
"Dawno has big sparkly ears" because she once had an avatar with that very feature...
Duh, there's probably lots of stuff in "AW culture" - there's an AW History forum around here somewhere that might have some of this stuff in it. Oh yeah, that's another thing, sometimes some people's avatars somehow magically change...
Oh and there's Phentermine.... well, sometimes spammers register just to post some ads and junk - the mods usually just delete those, but sometimes people respond before the mods get to the posts, and, well, this happened (you don't have to read the whole thread!):

And mention of Phentermine quickly spilled over into other threads, and now it's part of AW lore. That's kind of how things happen around here.
