Basically a bad motor scooter is a black, hard talking, hard hitting, hardcore guy who looks like he's hardcore-gaycore-noobsauce-elite at first then he turns out to just flat out rock your world and devastate your hopes and dreams of ever reaching a level of coolness as high as his.
The bad motor scooter tends to be quiet until you say something to him, then he comes back at you with some intense Mark Twain Shit that alters your entire perspective on the universal paradox of mankinds purpose in life.
He ends your eternal soul.
Serious man, the bad motor scooter is one bad motor scooter.
Kyle Nugent one-hits Nefarion, he's one one bad motor scooter.
