To Be In Surplus
To Remain Left Over, To Be In Excess
intransitive verb, godan verb
This word consists of kanji with hiragana attached. Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means surplus so the verb version would be to be in surplus, to remain left over, or to be in excess. Too much!
Something you don't want to be in surplus is armor (あま). Armor is heavy and it takes up a lot of space, so you need maybe one set at most. If you have enough for it to remain left over when you go off to battle, well, you probably have too much.
