hi-riser 

At first, a box Chevy on 20 inch wheels. More recently (2006) any older General Motors car on tall chrome wheels and preferably with outrageous candy color paint job, custom interior, big sound, and juiced up engine. A popular trend in the Southeast USA.

Hi-Risers have been appearing in numerous rap videos of late and are becoming the car of choice for the hood because of their bold colors and huge 'how the Hell did they make those fit?' chrome shoes.

Hi_riser 

The act of exercising arrogance toward their transfer from Corbin to Knox Central High School in Southeastern Kentucky. One may choose to personally refer to themselves as this or even secretly post on a "preppy" website as this screenname. In either case, the person is most likely in need of attention and craves any type of compliments, even if the best he could achieve is "yeah, hes okay..." This person probably feels that he is physically fit and very strong (possibly even go by nicknames like "king kong") when reality is that he is obese and plump due to steroid abuse. In this case alone, pathetic only begins to define this.
