ELI5: Does repeatedly flicking a light on and off damage it?

I was told flicking the lights on and off quickly damages the light (maybe the bulb, maybe the switch?). 

Any truth to this?

Probably.  Sending pulses of power into things causes a lot of stress on them.  This is particularly a problem with delicate things like light bulb filaments.  Plus it annoys the other people in the room and if someone throws a shoe at the lamp that could also damage it.
