The act of filling an egg roll with diarrhea and forcing into your partner's anus. Some even try to use a karatekick to jam it in there. Similar to a shit dildo but with a few more steps.
"Dude, that's the last time I hook up with an Asianchick. Last night, she tried to give me a Hong Kong Gooey when i wasn't looking."

Andy: So how did last night go Billy?
Billy: Man, me and the boys gave that bitch the Hong Kong Noodle Bowl.

A Hong Kong Finish is the name for what those weird pervert dudes in Hong Kong do to women on the subway. They rub on them and then “finish” on their clothing -- all while avoiding eye contact because Asian folks do not like eye contact, unless it’s eye contact made with a crying woman. That’s totally a thing over there! Anyways, that’s how it gets on the inside of jackets and backs of skirts. Everyone is in their biz casual attire on the subway coming home from work.
