Disco biscuit is a classic piece of drug slang with a dual identity. Originally it referred to Quaaludes — the sedative-hypnotic party pills that defined 1970s nightlife excess. Later, as the rave era hit, the term migrated to MDMA (ecstasy) tablets, which became the disco biscuit of a new generation dancing through the night. The name brilliantly captures the vibe: something small and round that you consume in a nightlife setting and that completely changes the experience. It's one of those slang terms that tells the whole story of late 20th-century club culture in two words.
The whole crowd was buzzing — someone joked that the DJ had been handing out disco biscuits at the door.
