One who slaps stickers, adds "body-kits", gets "altezza" tail lights, paint various/random parts with primer, gets a wing bigger than the trunk, and adds a fartcan exhaust or cuts off the exhaust to the catalytic converter to a car, mainly Asian cars such as a Honda, Acura, Mitsubishi, Toyota, etc. is considered a ricer.... Also people that add "under-glow" aka neon lights or any other pointless lighting that is not added to improve visibility but only for show. As well as a car that has a weedwacker sounding exhaust, a person who believes the more stickers the more horsepower, and a person who has no peformance modifications what-so-ever.. and painting engine parts or other misc items such as the interior is not a performance upgrade(s)....

"Dude Guy! I just added a new stickah to the windshield! It looks fahckin sweet matched up with the flames going down da car! It added 50 horsepowah! DUDE GUY! YEAH GUY!" or "Dude guy!, that exhaust sounds fahkin sweet! It MUST be fast."
