Get the Grushkin mug.
Diminutive employee at any occupation that constantly pretends to know more than everyone. They can be easily identified by their short status and likelihood to try and kill off the entire staff because he just had a hard time mounting a tire. They listen to loud terrible rap music and mix whey protein with cranberry juice. YEAHHHHHHH!
Oh fuck me here comes the Grushkin, everyone pretend to be busy.
