Get the Bum Clockmug. The cross-hatched webbing pattern that forms from dry dirty anal hair, so that faecal matter has to rip through like a child on a trampoline tower

Get the Bum & Cokemug. Yoon Bum is the main character from the manhwa Killing Stalking. He lost both of his parents when he was a little kid, he was then given to his stinky uncle and grandma wo lived in a poor household, Bum had to sleep on the ground and he was being abused, starved, and raped every day by his overweight uncle for years. He was also bullied in school and never had friends and then he was sexually abused in military. As if that wasn't already bad enough, Sangwoo then kidnapped Bum and verbally abused Bum for months. Bum's whole life was basically hell and all he ever wanted was for someone to love him for once. He received his first present ever when he was 28 YEARS OLD. This poor abused boy never had anything nice happening to him.
Yoon Bum is a orphan and lifelong abuse and rape victim who deserved so much better, preferably lots of hugs, therapy, and pet frogs (He loves frogs)
His name makes totally sense when you see his bum btw
