"Jackin" referred to a style of dance, today it is more commonly associated with a nuskool style of "primarily" sample-based house music called "Jackin House" which is characterized largely by its urban/urban feel. street. attitude, shuffly/skippy percussion, big funky bass lines and choppy samples from styles such as hip-hop, rnb, jazz, swing, funk and disco. This is generally a more "energetic" and "faster" house form normally falling between 126 and 130 bmp, but it can also contain deeper, moodier elements. This stays very true to the old house formula, but unlike more traditional styles which are limited to much stricter well-defined limitations, pretty much anything goes in Jackin House as long as it's not considered douchey or cheese and stays within these bpm ranges. Often jokingly referred to as "dude house" or "gangsta house".
