A crustinator is a tool used for the farming of bum crust. It is like a bread knife in that regard. When acquiring one make sure it's not sharp, as that may hurt yout bumhole. It doesn't just have to be used for the farming of bum crust but make sure you clean it before using it for any other practices.
Person 1: Hey (Person 2) did you get your Crustinator yet, I really need to farm my crust, it has been accumulating for 1 1/2 years now!
Person 2: Yes, I did receive it yesterday, but I need too farm first, and remember to clean it for the best possible results!

A Crustin is a kid who wears the same sweater everyday, often with a mismatched Yankees cap, maybe even a women's one. He also probably sports a classic bowl cut and listens to poser music, like Lil Wayne. A crustin is also said to have very little athletic talent or athelticism, but often tries as hard as he can.
Kid A: who's that kid in the yankees cap listening to lil wayne?
B: whatta crustin

Crustine is a wonderful streamer who also goes by the name HotnessSadline.

She received her name after producing crusty content. She is an avid fan of the epic games store in particular Dungeons 3 which was free on there for a short period of time. Some people say she's is still playing Dungeons 3 to this day.
Did you see Crustine's stream? It was so good this week! Crustine forgot to wear pants!
