Slang

Slang is the use of colorful words, derived from regional or time specific terminology, used in place of more formal words.

Many time frames and cultures have their own unique slang. For example, during the 20th century on Earth, several cultural movements had their own slang terminology. Starfleet officers who were involved in instances of time travel or other alien contact were sometimes subjected to a degree of social ineptness due to the confusion caused by the usage of slang.

Variations of slang
The Iotian culture developed on Sigma Iotia II built its society based on the novel Chicago Mobs of the Twenties. Therefore, the Iotians used many slang terms that were originally popular during the 1920s on Earth. 

Likewise, the holodeck program Bashir 62, used a lot of early 1960s slang.
