3. Don’t stare every single person in the eyes
Since the beginning of time, or maybe only since the 1980s, people have been staring each other in the eyes before taking shots to avoid being cursed with 7 years of bad sex. This is a terrible tradition -- not because it’s superstitious mumbo jumbo, but because staring each other in the eyes makes us look like silly crazy people, and looking like a silly crazy person is a surefire route to having no sex of any kind.
Let's bond together in friendship, and not mutual irrational fear that we might be making lousy whoopie for the next 2555 days.
