An older lady, usually in her 40's that is sexually active, often times with younger men. That was some "old biscuit" I had last night. A vagina is shaped like a "bicuit" that is pulled apart, hence the name "old biscuit".
like a cougar, an older woman that is on the prowl. I had some old biscuit last night when i banged her
