Kramer 

Someone who habitually bursts into doors unexpected. This can be at an office or at somebody's home or apartment. The intrusion causes negative attention from everybody in the room. It can disrupt conversation, ruin appetite, or cause a major cockblock.
In the tv show Seinfeld, Kramer is Jerry Seinfeld's neighbor who always opens the door to Seinfeld's apartment uninvited.

(Mark violently enters break room at the paper company and everybody looks at him)
Mark: Hey guys whats up?
Jan: Ugh, total Kramer.

Kramerica

Derived from the lexicon of Seinfeld, and more properly known as Kramerica Industries, it is a holding company for Cosmo Kramer's various (and often zany) undertakings.

Also may be adapted from the last name of anyone who really isn't doing much with his/her life.

Bushmerica Industries is really going down the shitter. Hopefully it will be taken over in November.

dirty kameron

When having sex. The male goes to the kitchen and grabs ice cream. Sticks his dick in the ice cream then shoves it into his girlfriends mouth.

My girlfriend begged for a dirty kameron.

Cosmo Kramer

The god of all that is holy. The man that can get whatever he wants including females. Someone that you aspire to be. The mr. cool of the 90's and arguably the funniest character ever on tv.

Yo, that Cosmo kramer is a real assman.

I wish i was like Cosmo Kramer.
