"Sucka" is the codename of a terran salesman. His number is 2625559650.
One of his advertised sales was that of the vulture once owned by Jim Raynor. Advertising it as a "great deal" and selling its shortcomings as advantages, Sucka placed a price of 65,000 credits on it. If a user payed in cash, they would receive free spider mines as part of the bargain in order to "pimp" their new vehicle.
