Top definition
A unique carnivorous mammal that can be found deep in the western suburbs of Illinois. Characterized by a rough, spiky exterior and its ability to impersonate other mammals like it which it does due to a feeling of inferiority and lack of self-confidence. The male mercasou is near extinction due to its innate characteristic that repels its female species.
The other day National Geographic had a special on the mercasou...did you know that it is actually white on the outside but black on the inside?
