Some dumbass YouTuber who likes to trespass on railroad property and thinks it's funny to tamper with railroad shit. It's all fun in games until he gets run over by that 4285 over there that just hit a cocaine truck.

But he’s also just a genuine person that I really like. He is super athletic which is 100% admirable. Sebastian is super cute and he is someone I really care about soooo

Get the sebastianmug. 
If you meet him the first time, you will wonder, how a person can be so smart and such an idiot at the same time. He is usually pretty funny but he can get pretty serious in sertain topics. A Sebastian Markus always gets girls way out of his league. He is not the perfect lover, but his girlfriend still loves him. He is a weired guy and his friends only stay with him to protect other people of him, but they are fine with it.
