Thank you everyone for your replies! I might have missed the last syllable when I actually heard maitta.
Is matte also used in judo? I remember hearing this but I thought matte means to wait, not to yield or stop.
Matte - "Wait."
Maitta - "I yield."
"Matte" wouldn't be used to indicate submission. An imperative form, "Mate" is used in judo as an instruction by the referee, generally meaning "Time (out)."
