Get the Bump-in-the-Night mug.
Someone that you ignore and find as irrelevant as hitting a squirrel in the middle of the night with your car.

Hitting the animal creates a bump that easily felt but subtle enough to where you think you've just ran over a pothole or some other object but you simply ignore as you want to carry on driving home from a long day.
Jimbo: Why are you even talking to me? I don't know you, you are nothing. You are just a Bump in the Night.

person 1: Woah, I heard she got STD's from her last bump in the night.

person 2: Yeah I feel sorta bad for her, dumb bitch, she was smexy though.

To get fully kitted with battle rattles. To investigate and harm people that'll harm you. Or others
