The potential side-effects include, but are not limited to: severe humiliation, emotional trauma, temporary to permanent paralysis of the face during Discharge, speech impediments, IBS, ED, and death.
Simultaneous discharges are as follows, in no particular order: tears, laughter, ejaculation, explosive defecation, projectile vomiting, coughing, sneezing, burping, and urination. Some cases have reported a brief scream prior to the simultaneous discharge. Causes are still unknown, and thus occurrences have been established to be completely random. Female cases have also been reported, and every side-effect is involved, excluding of course ED.
Victims of SMBFD have been known to lose consciousness immediately following the Discharge, only to regain it minutes to hours later. Unfortunately, amnesia is not a side-effect.
