clockblocked
trolliest AMC 10 problem in history (specifically referring to 2015 AMC 10A #14)
The diagram below shows the circular face of a clock with radius $20$ cm and a circular disk with radius $10$ cm externally tangent to the clock face at $12$ o'clock. The disk has an arrow painted on it, initially pointing in the upward vertical direction. Let the disk roll clockwise around the clock face. At what point on the clock face will the disk be tangent when the arrow is next pointing in the upward vertical direction?

Guy: Hey, how was the AMC 10 yesterday?
Girl: It went fairly well, except that I got clockblocked.
Guy: ( ͡° ͜ʖ ͡°)( ͡° ͜ʖ ͡°)( ͡° ͜ʖ ͡°)( ͡° ͜ʖ ͡°)
Girl: No, not "that" kind of "-blocked"
Guy: what the hell are you talking about then?
Girl: It was one of the problems on the AMC 10A, that problem about the disk tangent to the clock
Guy: Oh.
