It's one of the measurements they take at the re-draft combine. It's the measure of alcohol tolerance (Volume of Rum Punch). It's basically how many pints of rum punch a player can consume before they can no longer pass a sobriety test.
Because, he drinks like a fish.

Ok, that wasn't very helpful. The full formula and a detailed explanation can be found
here.
The complicated part is calculating BPM, once you have that VORP (Value Over Replacement Player) is easy:
"So, to calculate VORP, the formula is simply: [BPM – (-2.0)] * (% of minutes played)*(team games/82). This yields the number of points the player is producing over a replacement player, per 100 TEAM possessions over an entire season."
I also found this tidbit interesting:
"The beauty of VORP is that like WAR in baseball, it should track linearly with salary. A player with a VORP of 4.0 is worth, on the market, about twice what a player of VORP 2.0 is worth. Sometimes good players play few minutes for reasons outside their control, and would be worth more because they
should be getting more minutes. Still, for a crude estimate, VORP is valuable. It does measure fairly accurately what a player did produce in terms of value for a given team."
