of an opportunity to skip past

pass-out time to do something, to miss the opportunity, to lost the opportunity

time to slip away

(Vulgar) a dancer, a dancing-boy

an expression of mild surprise on someone's unexpected arrival after a long time

an arrow shot from the bow and a word said never return, a word and a stone let go cannot be called back

an opportunity to pass away, or escape, or be lost

to let slip an opportunity
