facebook fever - When you open a browser and type 'f' just because you know i

When you open a browser and type 'f' just because you know it's going to take you to Facebook, like you're a brain-dead robot.

I opened Chrome and typed 'f' because I was too lazy to type 'facebook. com'.

I typed 'f' in my phone browser and checked Facebook instead of doing my homework.

I opened my browser at 3 a. m. and typed 'f' because I was bored.
