A racial slur equivalent to nigger, but for Asian people.
"Oi have you seen Paul?"
"That nigga expelled last month."
"Someone seen his pot farm in the biology lab?"
"Nah he called Schuchang dirty ricer when he stole his speed from the PE locker."
"Ah fuck nigga, no other nigga but Paul would sell his shit to third graders, we're fucked mate."
"Better beat up that ricer."
