Biscuits can be sweet or savory. Sweet biscuits are cookies, as described above. Savory biscuits are what we would call snack crackers. "Crackers," for the British, are actually a kind of long and round party favor. You pull on both ends and a small cap "detonates" to create a cracking sound. Inside the cracker is a cheap toy, a party hat, and a printed comment like you might find in a fortune cookie.
