"To hit up", a term popularized by users of the social networking website MySpace, refers to contacting a person via electronic means.

"Hit Me Up" was used as the opening theme for Germany's Next Topmodel, Cycle 2 and as an official song for the 2007 CONCACAF Gold Cup soccer tournament.

It was featured in a Wheat Thins's commercial for garden vegetable flavored crackers and gained attention again when it was performed in May 2008 by Syesha Mercado on American Idol's seventh season at the top three stage.

[5] In the video, the focus is on the Happy Feet theme, with Gia appearing in three different sets with dancers in the background while singing the song.

The only indications of the song having been on the Happy Feet soundtrack are one, when Gia is singing in front of a theatre and above her the cinema's marquee displays Happy Feet, and two, when in the middle of the video her backup dancers are seen in tuxedos and wearing costume penguin masks as they dance in an arctic scene.
