Morning After Remorse Syndrome. The feeling of regret about the previous night's alcohol-induced activities. M.A.R.S. can have direct causes, such as engaging in buffoonery, or can be a general sense of remorse not attached to a specific incident. M.A.R.S. can exist separate from a hangover, as its effects are purely mental and emotional, rather than physical. (pronounced mahrz)
