the edge where full becomes too much, holding its breath before the spill
means The brim is the topmost edge or rim of a container, or the projecting edge of a hat — and as a verb, to be filled right up to that edge.
from From Middle English 'brim' or 'brimme,' meaning an edge or border, especially of water — a shore or bank. Its deeper roots are uncertain, but it's likely related to a Germanic family of words for edge and rim; some link it to an old sense of 'surge' or 'roaring water,' fitting for a word that lives where the liquid reaches its limit. The hat-brim sense came later, borrowing the same idea of an edge that juts out.
