To put it simply, high speed pcb design is any design where the integrity of your signals starts to be affected by the physical characteristics of your circuit board, like your layout, packaging, layer stackup, interconnections, etc if you start designing boards and run into problems like delays, attenuation. For a certain trace length, the signal needs a certain time to pass it, and this is called the propagation delay time.
