Means some thing is stupid or dumb.
No reason for it.
Sachey can also be used as an emphasis or another way of saying it.

a sachs farts when he is nervous, and while outwardly ashamed by the odor, he secretly loves it, wishing to bottle his aroma for perpetual sniffing. The sachs also has dual personalities. When around others, a sachs can be polite, gentle and subdued, however when in private, he will exclaim dirty profanities and do gymnastics while naked.
Steven was having dinner with several people and decided to be a sachs and farted, ashamed to admit it, but secretly enjoying it.
