Top Definition
A person born with a mental condition and therefore has to work a million times harder to be able to do simple things (such as learn and communicate) that we take for granted. On top of this, a guyonasm will usually suffer a lot of ridicule from society because people fear what they do not understand. The people who choose to make fun of guyonasm to be complete badasses and do not care that these people have feelings, emotions, and diapers just like anyone else.
Damn, guyonasm is a special one.
