Like rolling your own cigarettes (or growing your own weed), rocking a flask of alcohol is not only an interesting "You're cool" convo-starter, but it also saves you money. Yeah, it can sometimes come off as either pretentious or bum-like, but let the haters hate while you're drinking Johnnie Walker straight out the side pocket. Then, in a comically slurred voice, yell out: "I don't care what you think....I'm so happyyyy." And stumble away.

Flasks are a bit of an old-school accoutrement but they're making a comeback (just in time for the recession) with a lot of fresh new products. Along with a look at our top market picks, check out our guide to flask etiquette below...

WHAT:
So what's your poison? Whiskeys or vodkas? Doesn't really matter, but stick to one liquor so as not to dilute the taste. Mixing Jack and soda is not an option.

WHERE:
Pro sporting events are the perfect setting for a flask because getting drunk on stadium beer will kill your wallet. (Opt for a glass flask to dodge any metal detectors.) Other times for a flask? Jury duty, waiting at the DMV, grocery shopping, laying on the beach, zipping through traffic...wait. NOT zipping through traffic. Definitely not that one. Our bad.

HOW:
Keeping a flask inside your jacket pocket is ideal, but in the summer, the waistband of your shorts will have to do. You can also go cowboy-style and rock it tucked in your boots.

CARE:
Clean every two or three uses. Don't use soap. Pour vinegar inside and shake. Afterwards, rinse and leave with hot water overnight. This will help break down the alcohol—now you change up the liquor of your choice.
