I tried to add a definition for ギッタンギッタン to JDIC using references on the Internet.
http://www.edrdg.org/jmdictdb/cgi-bin/entr.py?e=1907714&svc=jmdict&sid=
They're slow to add it (or reject it) which is highly unusual. I'm guessing the provided references are not authoritative enough.
Would anybody have any good double checked references for this ?
the current definition I have is :
- (ギッタンギッタンにする、ギッタンギッタンにやる) to obliterate, to destroy completely, to inflict tremendous pain
