coolsies 

A "cute-ified" term for cool; similar to calling a sip of beer "a sippy of beer".

coolsie 

Derogatory Australian slang term synonymous with "hipster".

The term was once well-known in Australia -- especially amongst Melbourne youth -- but has fallen out of usage due to the recent explosion/influence of American hipster culture in the early-to-mid-2000s.

The inner-city is home to many coolsies.
