slacker-tude

A combination of slacker and attitude, these often appear together in one emotional package

Even with her work unfinished, she still managed to give me plenty of slacker-tude at the end of the day

Slackerdom

The state of slacking. Similar to how boredom is the state of being bored. It implies a deeper level of slacking off then merely saying "i've been slacking"

My week long slackerdom finally ended when I realized the test is tomorrow.
