*waacking! Sometimes referred to as Whacking, but most commonly spelled Waacking.According to the post, they are aiming to explore "lyrical hip-hop" as well as "Whacking".
Context (from wiki):
In the early 1970s a dance style known as punking emerged, with "punk" being a derogatory term for gay men at the time. The term "whack" was a specific movement within the punking style which involved moving the arms over the head in a rhythmic fashion. Although the wider club-going community took part in punking, they did not want the dance to have negative connotations attached to it and therefore renamed the genre "Waackin". Later, Jeffery Daniel added the "g" to waackin to make it "waacking", the name by which the style is commonly known today. The terms 'Whacking' and 'Wacking' are also occasionally used to refer to the dance style.
Wish they'd added vogue instead of lyrical hip hop though, never like that stuff.
