A joke developed in a highschool. A
school bus full of sus
boys going to a basketball tournament they know they were gonna lose.
One boy sent a pornographic image and from then on it was known as the sus bus. Now everybody says it, not knowing where it's from
Bob - "SUS BUS SUS BUS SUS BUS SUS BUS"
Jack - "pfft! do you even know where that's from?"
Bob - "why do you always have to ruin everything"
