In Gbaya, the notion of someone who is quick to speak in Proverbs 29:20 is emphasized with the ideophone putum-putum, which refers to the collapse of a hole, or falling into a hole hidden under the grass. Here the talker goes putum-putum into an obscured hole (i.e. fails) because they spoke to quickly.

Ideophones are a class of sound symbolic words expressing human sensation that are used as literary devices in many African languages. (Source: Philip Noss)
