Fratire

Fratire- Clothing that is stereotypical of a man in a fraternity. Typically preppy, bright colored clothing.

I found that using this term among my friends got a positive reaction. Depending on the context, people would continue to describe the same outfit as frat or being a fratire. The term did not really hold any long term presence but in the moment people thought it was clever.  Adults are not as familiar with the term frat and failed to find it as amusing.
