Backrock Water Park

When you’re in a public place late at night after any potential bathrooms are no longer available to you, so in desperation you end up peeing on a brick wall or other property. This spot effectively becomes your backrock water park and you’ll never be able to walk past it again without thinking back.

Blackrock College

A secondary school in South County Dublin where wealthy parents pay €20000 a term for their son to become a professional penis.

The students consist mainly of posh wankers who argue about whose daddy has more money. They usually go to school via private helicopter and enjoy extravagant ski holidays in Andorra on bank holiday weekends. They are often seen trying to act hard despite the fact that they're driving around in their daddy's Range Rover.

A noticeable characteristic of a Blackrock student is that they seem to be oblivious to the fact that they are absolute saps.
John: I'm going to walk over there and kick the shit out those four guys, simply because they go to Blackrock College.

James: Please do, but beware, their dad will most likely sue you.

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.
