Meaning
A smooth talker — someone with a honeyed, persuasive tongue who flatters and sweet-talks to charm, coax, or deceive. As an adjective, to be 'sweet-mout' is to be glib and flattering, all soft, pleasing words. The term cuts both ways: it can admire a person's charm and gift of the gab, or warn against the con man whose sweetness hides a trick. In a culture that loves and distrusts fine talk in equal measure, the sweet-mout is both prized and watched, his easy words never quite to be trusted.
Examples
-

-

-
A sweet mout salesman sell yuh anyting.
A smooth-talking salesman will sell you anything.
Origin
From 'sweet' (pleasing) plus 'mout' (mouth) — a mouth that speaks sweetly to charm or persuade.
