A term used in Jamaica to describe people who make negative predictions or hypotheses which actually turn out to be the case. (P.S. Thing said must be negative in nature)
Bob and Peter decide to transport 100 kilos of weed in their car. Bob gets cold feet about the plan and says to Peter: 'What if the babylon boys stop us on the road?' (Babylon ==Police). Peter says to bob : 'Stop being a little sissy and let's do this man'. They start to drive and on reaching a corner they meet up on some babylon boys who are doing a spot check and they get pulled over. Peter says to Bob: 'You know, you are a real goat mouth Bob?'.

Get the Goat Mouth mug.
When a female has a recessed chin making her mouth look like that of a Goat. There may be an overbite involved, possibly big gums, and may or may not be accompanied by other Goat like features. In serious cases the chin becomes one with their neck.

In these situations do not allow the male penis to enter the mouth of the female Goat Mouth. Often, jagged teeth from chewing on cans as snacks has ravaged the Goat Mouth which can cause potential serious male penis injury.
