What do all those abbreviations and terms mean?

As a collector of Funko Pop!'s you often hear different terms and catchphrases. This can be confusing, especially at the beginning.
Below is an overview of the most commonly used terms in the community:
General
ISO: In Search Of.
NFS/NFT: Not for Sale/Not for Trade.
LF: Looking for.
HTF: Hard to Find (rare).
OOB: Out of the Box.
Mail Call: Received a package and you want to show it to the rest of the members.
Differences between Funko Pop!'s
Vaulted: These Pop!'s are no longer made by Funko.
Grail: Pop! that a collector would really like to have. This does not necessarily have to be vaulted. Also, the definition of grail can be different for each person. What is a grail for one person may not be a grail for another.
Rare: Rare.
Exclusive: Released exclusively for a company or convention (e.g. NYCC, HotTopic, SDCC, Gamestop, etc).
Chase: Some Pop!'s have a Chase variant. This varies from 1 in 3 to 1 in 6. A Chase variant can be a different shape or just a metallic version of the same Pop!.
Oversized: These are Pop!'s that are larger than the standard 4". These are usually 6" and sometimes 9".
Conventions
NYCC: New York Comic Con
SDCC: San Diego Comic Con
ECCC: Emerald City Comic Con
DCC: Dutch Comic Con
Finishes
Metallic: Finished with a metallic paint.
GITD: Glow in the Dark (glows in the dark).
Translucent: (semi) transparent finish.
Flocked: The Pop! has a 'fur' instead of smooth plastic.
Patina: The Pop! looks like it has an oxidation layer.
STICKERS WHAT SHOULD I GET WITH IT?
This has everything to do with licensing.
America and European countries have different exclusives. Some stores in America buy rights, but this is only valid in America itself and not in Europe. They usually end up coming to Europe, but without a sticker. Unfortunately, this can take months. However, there is no guarantee that these Pop!'s will come to the Netherlands.
