HHOP meaning in General ?

Half Hour of Power is the debut extended play by Canadian rock band Sum 41. It was released on June 27, 2000 on Big Rig Records, a subsidiary of Island Records (United States), and Aquarius Records (Canada). The cover features the band's then-drummer Steve Jocz aiming a Nerf gun up in the air and standing in front of an explosion in the background. Though officially an EP, Half Hour of Power may also be considered the band's debut studio album. Most of the songs featured on the EP were included as bonus tracks on Sum 41's actual debut studio album All Killer No Filler, which featured a re-recorded version of Half Hour of Power's sixth track "Summer". This is the second of three times that this song was featured on a Sum 41 album. It first appeared on their 1998 demo tape. The group originally planned to include different versions of the song on each of their albums as a joke, but scrapped the idea after All Killer No Filler, as they felt that it would annoy their fanbase.
