What is meant by "finished with a super 'DAH'"? In chapter 196 of Beelzebub, after beating Nasubi, Oga buried Nasubi's doppelgangers into the ceiling, as shown in the image below.

Is there a meaning in the position of the bodies (with the reference of "super DAH")? Or is it just meant to be random?
The corpses form the Katakana character "ダ", which is pronounced as "Da".
