A adjective referring to
people or objects originating in the mountainous South
American nation of Colombia. The volcanic soil and humid weather makes for ideal coca plant growing conditions, and thus "Colombian" is generally used to describe good, high purity cocaine, regardless of it's point of origin.
Also, public opinion seems to hold that Colombian citizens and immigrants tend to have
big, round heads, though like most stereotypes, this probably would not hold up under serious scentific study.
In the film Scarface (1983), the title actor's first dealing with cocaine occurs during a drug deal gone wrong. Needless to say, both the drug and the
people who deal it are are columbian. The following is dialogue from that film:
Colombian: Yeah, okay, you gonna give me the cash or am I gonna kill your
brother first? 'Fore I kill you?
Tony
Montana: Try sticking your head up your ass. See if it fits. (an insult referencing the Columbian's big head).
