Usually referencing the act of or being of a person that is 'trying' to be or may 'be' on the cutting-edge of something specific, or in general (very obscure music, extravagantly violent Asian horror movies , etc.) to be cool and ahead of the norm, and is usually used as an insult in most contexts.Most people who get plastered with this label in a truthful manner, and not in an insult-like manner usually of which is improperly describing someones tastes in said things, are 'kids' or in general people who psychology have pushed themselves into a funnel of wanting to be part of something different because they can't fit in to anything else. Or to build a pseudo-ego to have something to be proud of, when in reality it is just making them look very dumb.
