### Alternative forms

* メンチ切(き)る (menchi kiru)

### Etymology

Phrase composed of メンチ (menchi, various possible derivations; see below) + を (o, object particle) + 切る (kiru, “to cut something, to cut across something, to break something; to do something boldly”).
Unknown derivation. メンチ (menchi) on its own generally means mince, as in mincemeat, ground meat. That does not fit this idiom, however.
One explanation is that メンチ (menchi) is an alteration of メンタ, as found in the synonymous Kansai expression メンタを切る (menta o kiru). In this, menta is an alteration of 目の玉 (me no tama, “eyeball”): /me no tama/ → /mentama/ → /menta/. The standard term 目玉 (medama, “eyeball”) is also used metaphorically to mean a glare, a stare; a scolding; compare English hairy eyeball, to eye. In this case, the phrase could be parsed as: menta o kiru → “to boldly eyeball someone” → “to glare in challenge”.
Phonetically, however, there is no clear mechanism for メンタ (menta) to change into メンチ (menchi). A more likely phonetic origin might be 面子 (mentsu, “face, honor”). In this case, the phrase could be parsed as: menchi o kiru → “to cut / break someone else's honor” → “to glare in challenge”.
The derivation may be a combination of the above, where menta may have been influenced by mentsu to become menchi.
