number 13

A combination of mayonaise, spicy mustard, Relish, BBQ sauce, vinegar, Arby's sauce, and Tabasco.

I havent tried it but I bet it would taste fucking disgusting.

Man, I tried drinking my diabetic friend's urine and it tasted like number 13.

Rule 13

In situations in which a temporary set of rules are necessary, Rule 13 shall always be "No one shall say bad things about another person". In addition to establishing a standard level of civility, it also forces the situation to have a minimum level of structure by requiring at least 12 other rules be created.

Person A: "You're such a tool, Person B."

Person B: "Hey, Rule 13, jackass!"

Person M: "Rule 13 times two..."
