The "BSC Days" - also known as BSC Daze - is the acronym of the words Batshit Crazy Days. Urban meaning of the phrase can be found here: Bat Shit Crazy Urban Dictionary.
Regarding Camelot Unchained, BSC is referred to the main "crazy" ideas of Mark Jacobs and City State Entertainment team about the game mechanics. They can be considered as the first content and gameplay revelation of Camelot Unchained. The event was first planned to go live months earlier than summer 2014. Due to several unplanned delays, it took place in July and lasted four days long. For that reason, the word "days" got ironically changed into "daze" by CSE team itself.
More infos about the delay can be found here: BSC Delay infos.
During BSC Days, CSE scheduled several presentations, live Q&As, contests, and much more. Among other things, the main objective of these days was explaining the basics of the game contents, such as the magic system, the combat system, the world map and crafting, as well as technical presentations from Andrew Meggs and the team.

- Mark Jacobs, during BSC days videos, appeared with an Hawaiian floreal shirt. That shirt was a gift to all Kickstarter backers for having successfully funded the CU project in May 2013.
- Crazy cartoon bats came in with the word Batshit, like cartoon ducks during Kickstarter campaign. These drawings are actually used for a particular on-air screen during CSE twitch.tv streamings.
