What the actual shiznits 

A more discrete term for “what the actual fuck?”
Todd sees a video online that is seriously absurd and weird. He wants to comment, “what the actual fuck?” To tell everyone else that reads the comments that he thinks this video is fucking weird. But, swearing is restricted in this comment section due to the guidelines. Todd wants to be smart, and knows if he comments what he wants to, his comment will be deleted, and his opinion suppressed. So, he comments, “what the actual shiznits?”. This leaves Todd with his opinion expressed and his account left without warning.

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.
