I am familiar with chouk bwa, souch bwa, or choukèt bwa which means tree stump.
It is very likely that 'cho bwa' is used in the outskirts of some regions of Haiti.
Chouk (souch, or choukèt) is a stump (of a tree, of a tooth); it is also the stub of a paper check …. yon souch chèk a check stub
It can be used as a verb “chouke” - to be planted, to be rooted
Example:Lè madanm nan tande se zen k’ap bay anba tonèl la, li vin chouke kò l la, li pa janm deplase.
When the woman heard all the gossips spilled under the “straw” shed, she came and planted herself there and never moved.
byen kore, or byen chouke, or byen plante – firmly rooted
