silent but deadly
Odorous without warning
Silent but deadly describes a fart that makes no sound but has a notably foul odor.
The phrase plays on action-movie language about covert threats, applying it humorously to flatulence that announces itself through smell rather than noise.
It often appears in the abbreviated form SBD.
He let out a silent but deadly one and nobody knew who to blame.
