GMG
GMG is a Filipino expression which means "Google mo, gago!" It roughly translates to "Google it, you fool" and is an apt response to people who are asking about things where in fact, they can hit Google and do a simple search. Popularized by renowed journalist, poet, and jazz frontman Lourd de Veyra in a graduation speech he delivered in 2012.
