Gweilotine

A portmanteau of Gweilo (a common Cantonese slang term for Westerners. In its unmodified form, it applies on the light skinned people and has a history of racially deprecatory use) and guillotine (a machine with a heavy blade sliding vertically in grooves, used for beheading people)... you get the idea

Mike smoked marijuana while on vacation in China, was caught by the authorities, and was immediately sent to the gweilotine, without trial. Be smart. Don't be like Mike.
