"Teabagging" is a term in sailing for an action by a helmsman to heel the sailboat to windward (generally by steering to windward or easing the mainsail) too quickly for the crew, who is hiking out on a trapeze, to react to the change, dipping the crew into the drink. This generally makes the crew pretty salty and can capsize the boat. This can happen inadvertently as a result of a sudden lull in wind strength.

Excellent technique for dealing with annoying crews as they are pretty much helpless if the heel is changed quickly enough.

A teabag is a sealed, fine-pore cloth or paper pouch containing whole or chopped tea leaves and/or herbs. When the bag is dipped in hot water (a process known as steeping), the essence of the leaves and herbs infuse into the water. The bag prevents mess and accidental ingestion of the tea leaves.

Tea bags are convenient. They’re disposable, which means you don’t need a metal tea infuser to make a cup of tea. They’re single-serving, which means you don’t need a teapot. They’re biodegradable too! Tea drinkers worldwide should rejoice at this wonder of American ingenuity!

The tea bag was invented in 1904 by a New York tea and coffee merchant named Thomas Sullivan. He decided to package loose tea in small hand-sewn silk bags as an inexpensive and convenient way to distribute tea samples to his customers. To his surprise, his customers brewed the tea in the tea bags rather than removing the contents, thus giving birth to the tea bag.

The Sir Thomas J. Lipton company further improved upon this invention with the introduction of the Flo-Thru Tea Bag in 1952. With four brewing sides, rather than two, boiling water reaches the tea more easily, releasing more of the Lipton “Brisk” tea taste.

Lyons Tetley introduced the round tea bag in 1989 in the UK. At the time, Lyons Tetley was the number two brand in the UK, and like other major brands it was slowly losing its market share to the cheaper generic teas. Then, someone came up with the idea of introducing round tea bags. After Tetley started using them, sales immediately started to grow, increasing inventory turnover by 30%. 18 months later, Lyons Tetley regained brand leadership and has since maintained a 3-4% market share lead in the UK and made significant increases in its worldwide market share.

Since their introduction, the round tea bag has been copied by other companies, most notably by the Republic of Tea, who sells their teas in round tea bags stored in a round cylindrical tin, much like Pringles packs.

But according to a recent study of the kinetics of tea infusion, South African researchers found that it’s the size and not the shape that is important for good tea infusion. The bigger the bag, the more room there is for the flavor to flood out of the tea leaves, regardless of the shape of the bag. Tea leaves swell when infused in water, so water doesn’t flow efficiently through the leaves in the center of a swollen clump of leaves in a small bag. So a voluminous bag seems to be the answer to good tea infusion kinetics. But in the end, it’s the quality of the tea in the bag and not the size or shape of the bag that decides what makes a brisk cup of tea.

How to transform a tea bag into a single-use hot air balloon

You will need

What to do

  1. Remove the dinky little staple from the top of the bag
  2. Unfold the bag completely and dump out all the tea
  3. Straighten out the bag so you have a nice little cylinder
  4. Stand the cylinder on a table
  5. Light the top of it on fire

The tea bag will float about a meter and a half into the air, then gently come back down.

As a verb, to "tea bag" is sexual slang describing when a man dips his testicles into someone's mouth as a form of oral sex or rubs them against someone's forehead. This can be done either for sexual satisfaction or as a practical joke on an unconscious or sleeping victim, oftentimes taking pictures for greater humiliating effect.
