Ka-Plop
Ka-Plop is the equivalent of manslaughter suicide. It is when the suicide is unintentional, like an overdoes when an addict is clearly warned that is too much but insists they know what they are doing and the thought they might overdose is dismissed out of hand, only to find they did indeed overdose. Or when a lame-brained idiot thinks they'll walk along the edge of the 50th floor of a high-rise apartment building, never considering the fact the winds are strong and they could easily be blown off the roof, and guess what? That's exactly what happened. (Though that can also be classed under Ka-Splat!)
Ka-Plop. When Phillip and other members of the alien investigation team came across the very menacing looking alien, the other members all groaned "You ka-plopping idiot" when Phillip poked the many-fanged alien in the eye. "For love of Ka-Plop" was uttered by the recovery team when they found the shredded remains of the investigation team. The irony of the conclusive results of the investigation did not escape the recovery team.
