First seen on the "Awesometown" pilot. The group high fives each other all at once, at which point in time an explosion commences betwixt their hands.
2: A good way of knocking someone over, preferably off some kind of drop into a body of water. Must be done with a friend or more (two or more to explode another away) in order to make it a true Exploding High Five. For extra emphasis, precede it with a phrase, spoken in unison: "Thanks for coming back, *clap* *clap*, Exploding High Five!" Follow immediately with collective hand contact accompanied by an explosion noise via mouth power. Only to be used when one friend/acquaintance is being a duesch, jerkwad, jerkass, or some other such negative adjective.
2: (whispers) -- "Hey friend no. 2, that friend no. 3 of ours over there is being a jerkass, don't you think?"
(whispers) -- "'Deed I do, friend no. 1. Whatsay we do something about it?"
(whispers) -- "Whatsay!"
"Hey, friend no. 3!"
"Hey, friend no. 2!"
"High five, friend no. 3!"
"Sure, friend no. 1!" (friend no. 3 raises arm with back towards theoretical body of water)
(friends no. 1 and 2 in unison) -- "Thanks for coming back, *clap* *clap*, Eploding High Five! *bloosh*"
