Mo

A name for someone who is socially awkward (i.e. suggests morbid inner thoughts and awkward conversation topics) and has a tendency to screw things up, known as "mo"-ing, or "mo"-ing up.

If someone left a glass with water outside in the winter and it cracked, then they mo'd it the fuck up.

if someone breaks a valuable possession (i.e bong) in the process of doing something they think is good for it (i.e. cleaning) then they mo'd.

Mo example in speech:

person 1: "... so then he said-"
person 2: "-hold on a sec, i have to go take a shit. come to think of it, I might eat some food while im in there. Im thinking bananas and club soda. be right back."
person 1: ".....wtf? fuckin mo."
