轟く（とどろく） means “to thunder,” “to roar,” or “to resound,” often describing a powerful sound or presence that reaches far and wide.
In the song, FRUITS ZIPPER sings about becoming a 轟く存在, a presence that resounds throughout the universe. This vivid, dramatic verb makes the group’s cheerful “power” feel cosmic and unforgettable.
This song is a pun machine, and the pun is spelled out in the first verse. Hold "右手に「ぱ」" [in your right hand, "pa"] and "左手に「わ」" [in your left hand, "wa"], put them together and you get "パワー" [power]. Do the same with "this" and "that" and you get "らぶ" [love]. The endless "papa wawa" chant is just those two syllables bouncing around, so the whole chorus is the word power broken into pieces.
Then it goes full list mode. "パパパワー ママパワー" [dad power, mom power], grandma and grandpa power, the person you like, and my favourite stretch: "ごはんのパワー おやつのパワー" [the power of meals, the power of snacks] and "おふろのパワー すいみんパワー" [bath power, sleep power]. It is a bit much, and that is the point. Everything small in your day counts as fuel, all added up into "フルパワー" [full power].
The verses treat feelings like a phone battery: "充電まっててね" [wait while I charge] while she stores up "愛" [love] and "好き" [liking]. There is also a cute writing joke for learners. Take the little circle off ぱ and it becomes は, so "あわせて「はわ?」" [put together, "hawa?"] turns power into "ゼロパワー" [zero power]. Watch for "お手を拝借" [may I borrow your hands], a set phrase Japanese people use before a group clap, which here slides into wanting to hold hands.
