The act of dialing a phone number and letting it ring for no more than three seconds. Popular in Nigeria where 'flashers' are usually piss poor teens/adults low on airtime. The act is very annoying to the individual being flashed as the unwritten law is that you have to call back immediately, but again it is very economical to the 'flasher'.
