甚
shèn
excessive; undue
to exceed; to be more than; very; extremely; (dialect) what; whatever (Taiwan pr. [shen2])
sweet (甘) + match (匹) = so sweet it exceeds all measure
甘 means sweet or pleasant, and 匹 here is likely phonetic rather than contributing a clear semantic thread. The combined idea of sweetness taken to excess captures the sense of something being more than enough — indulgent, extreme.
