"on accident" again

[Laurence Horn]

Just before the end of regulation in tonight's playoff basketball
game between Detroit and Philadelphia, now in overtime,
Philadelphia's Eric Snow was described by Sean Elliot, one of the
announcers, as "kicking it [the basketball] on accident", sending it
out of bounds.

Impossible for me, but evidently not for other grown-ups. (I don't
think we ever decided whether it was regional or not.)
