I'm on jisho.org trying to figure out what association he makes for "Ikeda" at the end. I found that "ike" can strengthen a derogatory adjective, and "da" can mean "worthless," but I'm not sure he's that mean.
@HighStream "Ike" is also the imperative form of "iku", meaning to go; "da" can also be seen (depending on context) as a more emphatic "desu", turning a statement into an exclamation. Putting the two together would result in something like "Let's go!", which would fit Ikeda's seemingly energetic personality. Plus, the guy with him said "Let's go, Ikeda", making it something of a pun.
