Just how bad is it to plug a power strip into an extension chord into the wall?

I had a perfect setup in my room. There was a power strip next to my bed that had Christmas lights plugged into it that went all around the room. Therefore, when I have a guy over I can stealthily push one button to turn on or off the lights.

I just rearranged my room (better feng shui) and my bed is not near an outlet. I don’t want to have to get up and cross the room to alter the mood lighting:)

Am I going to light my house on fire if I simply use an extension cord with the power strip?

Sorry for the typo in the question, I’m a music nerd.
