n. A person who is arrogant, silly (in a ridiculously exaggerated sense), or simply funny in a very unorthodox manner.

adj. When something is funny, but only because of its sheer idiotic nature. Ex: "What a momon joke!"

Etymology- Some historians believe the word comes from the latin or modern Spanish/Mexican word "Mamar", which means to suck. After such massive immigration from Latin America, the word must have later evolved into what we now often use in the workplace or school.

When you eat dirt for the first time and leave your family to build a shack in the woods
