If while attempting to perform a Boston Pancake or Cleveland Steamer, and the fecal matter is not in solid form, it then becomes an Atlanta Hashbrown. You may not notice until you hear or feel splatters on your partner or your own anus. This often occurs after a heavy night of drinking. "Ice" beers (such as Icehouse) or Mexican food will facilitate in this act.
Although the Mexican food and Bud Ice from the previous night prevented Ted from achieving the Boston Pancake, the Atlanta Hashbrown was a comparable substitute.
