Esquire is definitely one of the most trusted sources on all things ‘manly’ worldwide, so when Esquire says these are the rules for manly drinking, you listen.
For example never take your drink through the straw.
Also talk half as much as you listen.
At the office party, always have one less drink than your boss.
