In the video, a fraternity of college geeks throws a huge party to "prove to the world that the nerd brigade knows how to rock". One member is tasked with getting lots of beer; another is assigned to find hot women to attend the party. Then another member arrives after having kidnapped Nickelback to play at the party; the fraternity leader however remarks "... Nickelback? You got me Nickelback?! ... Alright, fine, they'll do." The party then proceeds as Nickelback are forced by 2 football players, after the leader says, "Boys, get 'Em in there!" to play their song.

The video for "This Afternoon" was first shown on the Fuse website and can now be seen as their 'Video Of The Day' for 1 May 2010.

The song contains strong lyrical content suggestive of cannabis use and production, including an allusion to Bob Marley as well as Cheech and Chong.

During the week of June 4, 2010, the video debuted on CMT's Top Twenty Countdown at number 18.

The song has been a success on the Billboard Hot 100, peaking at number thirty-four. It is the band's highest charting single since "If Today Was Your Last Day" and is also the band's 10th top-forty song.

In Germany, the song debuted at No. 84, but climbed quickly. In its third week it reached the top fifty by jumping to No. 49 and in its seventh week it entered the top thirty by reaching No. 29
