If one from New York were to post a picture with the cation saying "QGTM" or "#QGTM," they mean "Queens Get The Money." The purpose of this is to pay homage to the borough of Queens - located within NYC -, commonly used by rappers from there. (Ex. Nas, Mobb Deep, Capone-N-Noreaga)
From Mobb Deep's song, Give Up the Goods (Just Step) , "Hey yo Queens get the Money long time no cash."
Here we see QGTM being used in their song, to pay homage to the borough where the rap group resides.
