Originating from a student trend in Brighton, England, of adding soy sauce to home-made cocktails, it is the name used for those who often chunder after extraneous amounts of alcohol yet know how to enjoy it before the unfortunate incidents. Also known as Lucys.
Simple. Sauce that looks like vomit. Often tastes like it, too. Usually given to you at Olive Garden. Your friends dare you to lick it. You do, and it tastes like barf mixed with a bit of your mom. Then when you come home, it turns out you have diarrhea. From the sauce or the food with the sauce, who knows?! You use all the wipes and go to bed right after that, afraid that diarrhea will happen again.
