State Patricks's Day 

A holiday created by Penn State students in 2007. It was celebrated on March 2, because spring break was scheduled over St. Patrick's Day (March 17). Many students begin lining up outside of bars and drinking as early as 6AM to celebrate. The festivities last the entire day as students wearing green show up drunk to class, or don't go at all. Many parties are held at night, featuring green beer and green jungle juice.
Student: Last night was ridiculous, I had so much fun celebrating State Patricks's Day!

State Patty's Day 

The drinking holiday in State College, PA that takes place once every year, usually in February. State Patty's day was created in 2007 when Saint Patrick's Day fell on spring break. Students still wanted to celebrate the drinking holiday with their friends at school, so they created this faux-holiday. The holiday has been growing in popularity year after year but is very controversial because of the large number of people arrested and sent to the hospital for alcohol poisoning.

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.
