A large or obviously sham filled situation that is doomed to failure, but much like the lemmings you can do nothing to stop it. Just hope when you encounter it in the wild that you are a voyeur and not a participant.
Johnny could obviously tell that the lemmings' summer retreat seminar and the Acapulco cliff diving competition was a cluster waiting to fuck and luckily he brought lube and a tripod.
Excursive phrase popular around UK, Ireland and Australia. Generally said when a higher authoritative figure asks what a youth or group of individuals are doing. Made even more popular by Clinton Smith on an Australian police show when asked what he was doing in a crashed car clearly drunk he simply replied "Just waiting for a mate"
John: Hey man, what you doing here?
James: Waiting for a mate
Peeler: Alright lads, what do you think you're up to?
Chavs: Waiting for a mate
