The random musings of a youth who is often innocent in their belief that the question is not stupid. It nearly always has no context to the current situation or conversation and appears random. It is often hilarious, distracting or even draining to the target or audience.
Whilst at work or lunch seemingly from nowhere they will ask things like "is an albinos poo white?" and "what would you do if the whole chinese army appeared outside ready to attack right now?" - This is a sebism.

An instinctive and sarcastic commentary without any real purpose or reference. A sebism is often used to cause confusion and laughing.
