A symbol that is a letter U with the arrow pointing down through the middle, which originated in Oahu, Hawaii. The symbol can be seen on cars, clothing apparel, and often times on the high over pass freeway signs. The symbol stands as a question to you, asking "are you down for some crazy shit".

A symbol more commonly found in Hawaii on clothing, cars, surfboards etc. and the every now and then highway sign. It’s a symbol that is in the shape of a U with an arrow pointing down in the center. Meaning, are udown to do this crazy antic/stunt? Referred to more as are “udown4sumkrazyshit?” starting off as an underground company which is now blowing up and starting to take notice in many foreign countries like Japan, China, Hong Kong, England, along with U.S.
