This video is from a rap artist called, Chuggo. Gary Switling is a Canadian rapper and currently his most well-known song is “Ah C’on from his album “Act Like you Might Know”. Chuggo started out by going to rap battles in Toronto and then released his first album in 2003. The album, act like you know, was released in May of 2005 and received good reviews in Canada. His internet fame began when the website, Something Awful, featured his song on their site in April of 2008.
If you haven’t figured it out, one of the reasons people though it was so funny was because the song could be misread as meaning to say, “Ah, come on, fuck a guy.”
