Let's see, the title of the OP is MAN LAW. Not etiquette or time-of-day or what have you. So:
Nothing sweet, ever. This includes rum & coke.
Stay season-appropriate. Whiskey in winter, gin-and-tonic in summer.
Straight shots aren't really grown-up. It looks desperate to get drunk. Now.
Martinis may pack a wallop, but the straight up ones in the pretty stemmed glasses are just so fem. Have them on the rocks with olives.
P.S. Rebel, that's the most dreadful thing I've ever heard of.
