Slang can start silly but end up rooted in the lexicon.

Also I consider it evolution when it comes from an older version of the word. Like swagger and swag. Swagger dates back to the 18th century.
I think it's creative.

Plus a lot of fake words become real after a fashion. See: normalcy

Me and my friend would be like "hopped up off the train, turned his swagggg on" Cause we totally made a parody of Soulja boy and draco malfoy.
