Filthy, one of Seattle's favorite slang terms!

<<< Back to Slang USA Cities Map
(adjective) Really cool; excellent; very good

“Filthy” can be used to emphasize how extremely cool something is. Here's how that might look. 

Brian: Kevin's new Porsche is pretty cool.

Brad: Nah, man. His new Porsche ain't pretty cool. It's filthy!

The term became popular in the 90s among youths, and is still used today in the Pacific Northwest by people in their 30s or younger. 

Seattle-based artist Macklemore sings “But my, my, my, my city's filthy” in “The Town” from The Unplanned Mixtape (2009).
