One of the earliest documented records of slam pong comes from Chris Robinson, Dartmouth College class of 1986, who recalled playing slam pong when he was an undergraduate. An article in the March, 1986 issue of "Playboy" magazine describes slam pong being played by the brothers of Psi Upsilon at Dartmouth. By the early 1990s, slam pong was played in nearly half of all Dartmouth College Greek organizations, and had been introduced to other colleges including Bowdoin College, Bucknell University, Cornell University, Lehigh University, Princeton University, and Williams College, but by the middle of the decade was beginning to decline in popularity. By the early 2000s, slam pong had been almost totally eclipsed by other variations of beer pong, especially "Beirut", one of the first variations of beer pong to be widely played across the country. At Dartmouth, lob became the standard variation of beer pong played by undergraduates.
