look up any word, like the eiffel tower:
An infamous bromance/ship that exists between two young men who are destined to be the world's greatest bros/lovers for all eternity. Punbun is commonly known as what gives life meaning and the point of mankind.
"Man did you see how fucking cute punbun was yesterday, playing with each other's hair and shit" "yeah man, I wish that me and MY love could be as perfect as them"
