think Harakiri is the proper, and "committing 'Harry Carry' " is slang for it.
it means to commit suicide.
"In American media, particular television and film from the 1940s-1960s era, the term "hara-kiri" was often mispronounced and misromanized as "Harry Carry". (See, for example, the TV series McHale's Navy). In the 1980s, it was morphed to "Harry Caray", due to the popularity of the eponymous baseball announcer."
