Reading fan posts throws up abbreviations constantly. The ones that come up most.
The whole stretch of releasing an album and appearing on shows is called a promotion period, and its end is the close of promotions. Releasing a new album is called a comeback, which does not imply a return from a break so much as taking the stage again with new material.
Appearing on a music show is often shortened in Korean, and a video shot focusing on one performer throughout is called a fancam. A separately filmed video showing the full choreography is called a dance practice or performance video.
The photo cards inserted at random inside albums are called photocards, often shortened further. Gifts given only by a particular retailer are called bonuses or benefits. Swapping a card with someone else is a trade, and since condition grading varies by person, confirming with photographs is safer.
Groups generally have an official fandom name, and often an official lightstick and colour as well. Chants performed together by the audience at set points in a song are called fanchants; the content differs by group and is usually announced through official accounts.
Fandom vocabulary appears and disappears quickly with trends. The same abbreviation can carry different meanings across groups or regions, so asking about an unfamiliar term causes fewer misunderstandings than guessing. Saying you do not know is generally received better than using a term incorrectly.
