The term for when a teacher gives you a discipline notice form (detention, suspension, etc.) that is so funny one should frame it and hang it on their wall in a place everyone will see. It should be seen as a badge of honor.
Person 1: my detention form says he yelled "oh shit last one in is gay!" Twice.
Sexual intercourse that takes place up against a wall, usually furtive. Most often takes place due to not being able to share a bedroom with one's love when visiting family for the holidays, because of strict parental guidelines, regardless of one's age.
While everyone was in the dining room feasting on the Christmas goose, Mark and Christine snuck around the corner by the den for a wallbanger before dessert arrived on the table.
A sunburn or suntan focused on the left arm. It is caused by the left side of the body being the only half that gets exposed to sunlight while driving. Presumably, it would be located on the right side of the body in countries where they drive on the left side of the road.
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.
