WE ALREADY HAVE ORIGINAL SLANG??? woah

Not a word, but instead a style of thread on Boards. The hashtag (#) is usually used before each line of a story on Boards to differentiate the experience and the actual content of the thread, this is where the Hashtag style gets its name from. Best example of something similar to this outside of Boards is 4chan's "greentext". Ironically enough, the hashtag style was actually first used by a 4channer who found boards and decided to convert a common greentext copypasta to a more Boards-friendly format.

An incel is a member of a community who consider themselves unable to attract women. When most people use "incel", they are most likely referencing incel culture and not the definition itself. Technically, you don't have to fit in the definition of incel to partake in incel culture.

Old-school internet slang meaning something along the lines of "Entertaining and humorous", think of "lol". Unlike "lol" though, it's almost exclusively used at the expense of someone or their experience.

A channy (plural- channies) is a shortened version of "4channer" invented by an anonymous Boards user. It is a person/group of people who found out about Boards through the 4chan imageboard. Most dislike them because of the toxicity they bring to boards. A recent spam attack was (most likely) caused by a group of channies.
