CRASH COURSE IN `SEIN' LANGUAGE.

Byline: Keith Marder Daily News Television Writer

Just as ``Star Trek'' has an entire ``Klingon'' language, ``Seinfeld'' has its own ``Neurotic New York'' lingo.

The ``Sein-Language,'' not to be confused with series star Jerry Seinfeld's best-selling book of the same title, has become as much a part of pop culture as the hairstyles of the ``Friends'' cast.

Every episode had some kind of made-up expression about something that each of us encounters in everyday life. It is the kind of observational humor that made Seinfeld a star.

Here are some of the more memorable descriptives the show has unleashed on America and their meanings.

Baldist: Someone who dislikes bald people.

The Beast: A rancid body odor that is stronger than any remedy. It forced Jerry to throw away a car.

Bro: See manssiere.

Close talker: Someone who invades your personal space during a conversation. Elaine dated one of these.

De-gift: To take back a gift. It would be described as Indian giving but that saying once got Jerry in trouble. When the Drake broke off his engagement, the gang ``de-gifted'' a big-screen television set.

Double-dipping: The unhygenic act of dipping a chip, taking a bite, and putting the chip back in the bowl for a second dip. It has been compared to licking the entire bowl.

Festivus: A December holiday not affiliated with any religion. It ends after the act of strength. Invented by Frank Costanza, an embarrassment for George Costanza.

Get out!: Disbelief. Short for, ``Get out of here!'' Elaine usually says this, followed by a two-handed shove.

Giddy-up!: Let's get it on! Let's go! An exclamation by Kramer, known for exclamations.

Hello, Jerry: See Hello, Newman.

Hello, Newman: A salutation for an archnemesis. It is what Jerry says to his chubby postal worker neighbor, Newman. Newman usually answer with an equally glum, ``Hello, Jerry.''

High talker: A man who talks with a womanlike high-pitched voice. One of Elaine's friends was in a relationship with one of these.

Low talker: Someone who talks at decibel levels too low to be heard.

Manssiere: A bra for men who need some support in their chest area. An ill-conceived get-rich scheme from the minds of Kramer and Frank Costanza. Also known as a ``bro.''

Mimbo: A male bimbo. Elaine dated, and George became infatuated with, one of these (played by Dan Cortese).

My boys can swim: Fertile. George proclaims this after he passes a fertility test.

Not that there's anything wrong with that: It's OK to be gay. After Jerry and George deny they are romantically linked, they make sure to be politically correct and add the tag.

Re-gifting: When you give someone something that someone else gave you as a gift. Tim Whatley gave Jerry a label maker that Elaine had given to Tim.

Serenity now: A relaxation mantra. Used by hyper, frenetic Frank Costanza.

Shiksappeal: Attractiveness you find in a non-Jewish woman.

Sponge-worthy: A man good enough for a woman to use her favorite kind of birth control. Elaine considers the contraceptive sponge, which has been discontinued, to be the best method.

Yadda, yadda, yadda: A way to complete a thought without giving all the details. George's girlfriend used this as a method to leave out minor story twists such as the fact that she is a shoplifter.
