expression
no problem; it's fine; don't worry
Casual expression borrowed from Cantonese 冇問題 (mou5 man6 tai4). Used in Japanese to mean 'no problem' or 'it's okay', often in a lighthearted or informal context.
from Chinese
「遅れてごめん！」「無問題、気にしないで。」
"Sorry I'm late!" "No problem, don't worry about it."
このくらいの仕事ならモーマンタイだよ。
This much work is no problem at all.
Borrowed from Cantonese 冇問題 (mou5 man6 tai4), meaning 'no problem'. The kanji 無問題 are a direct adaptation of the Cantonese characters, and the reading モーマンタイ approximates the Cantonese pronunciation.
