An abbreviation of Gambian Maybe Time. Refers to the system of time used by Gambian drug dealers. This system operates through a synthesis of optimistic time keeping and sheer apathy towards the customer. Although a precise written system is difficult to establish due to the complex nature of G.M.T, there are conventional assumptions usually made about the Gambians estimation. Five minutes is usually interpreted as twenty minutes and multiplied accordingly. However, this system is unreliable as G.M.T varies by environment, weather, micro-climate, lunar alignment, location and must importantly, the amount of money that is to change hands. Rare cases have been noted where Gambians have travelled vast distances in times thought impossible for human beings when asked to supply over 1OZ.
Gnash My Teeth. Deriving from Mary Shelley's Novel Frankenstein. The Character Victor Frankenstein constantly gnashes his teeth when something is wrong. Generally used when something unpleasant occurs.
