In order to win by blunt cup in beer pong a team must make every cup other than the middle cup without a re-rack. Once the last cup (middle/blunt cup) is made the opposing team will then owe the other team a blunt to smoke.
"you cant get blunt cup if you re-rack"

"Blunt cup is rarely achieved and is known as the holy grail of beer pong."
