HMU

Hit Me Up

The internet acronym “Hit Me Up” or HMU as it became to be known, went from being a relatively unknown term in 2009 to one of the most popular trends of 2010. HMU was literally unheard of in 2009, many instances attributed to user error. In May 2009, it was averaging 20 mentions a day, doubling each month to be mentioned in about 1,600 posts a day by the end of the year. Even though it grew quite substantially, it failed to make last years list.
