亜両面ありゃんめん

noun

inferior double-sided shape; incomplete chow with pair overlap; tile pattern 3345 or 3455

Mahjong term. Refers to a shape that waits on two tile types but is weaker than a standard リャンメン because two of the winning tiles are already used in the hand's pair, or a complete chow plus an adjacent tile that creates a similar wait.
