This is not a standard word that can be found in regular dictionaries.
It’s a Taglish term whose root is the English word “pose” (as in pose for a picture).
Pumosing pa sila sa may daan.
They even posed by the side of the road.
It doesn’t necessarily have to be really posing for a camera. It may also mean to behaving like you’re a model posing for a picture.
