Attention Span Ponzi Scheme 

An Attention Span Ponzi Scheme is a system of recruitment of people to pay attention to a topic. People recruited to the topic are then encouraged to drag in the attention spans of others.

The entire system collapses when everyone realizes that the topic is bankrupt of value to be discussed in the first place.
Examples of Attention Span Ponzi Schemes include chain letters, time-wasting Facebook applications, and any social reference group that is based on recruiting others to participate or play for the subject to have sustained interest.

Ponzi Gangbang

An orgy hosted by a couple of enterprising young men. These men provide at least 1 woman and promise a huge orgy to everyone who can bring along a woman. The first guys who host the gang bang, have little investment, since they can make the guys who come later provide all but one of the women, and pay for the hotel room. As long as there is a good pool of fresh women, all of the late comers will not notice they are being fucked.
Last Friday Dave and I, hosted a 14 hour Ponzi Gangbang. I had to leave after I had been with my 9th woman of the night, but it was cool since we got them to pay for the hotel room.

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.
