1.) Adjective, British slang. A modern-day phenomenon, often used to describe a mix of quirky, strange, flamboyant, oblivious, annoying, excitable, and idiosyncratic behaviour. Physical appearance can often be classed as nickosee, particularly lankey, awkward, or elaborate in nature.

Invented in North West London, England, nickosee is often misunderstood, and only a handful of individuals understand its true meaning. The concept was invented by an individual called Sam, when he witnessed his cousin frantically dancing when they were both 6 years old. She fell over, looking hot, embarrassed, and exposing her knickers. Sam exclaimed to his family "Urgh she's all knickers-ey!". The word then mutated into nickosee, and is commonly used in the North West London area by a select few people. Recent findings have shown it to have spread to an elite number in Leeds and beyond.

The word nickosee can be shortened to nik.
