It is the world's dumbest animal.
I have recently started calling dumb guys opossum.
eg: You are a bloody opossum
Figuratively: Someone whose shitty driving will soon cause them to be found dead on the road, just as actual opossums are often found.
(You are on a 3 lane freeway in the Summer. A person driving 45 mph, goes from the right lane to the middle lane, directly in front of you, without using their turn signal)
YOU: (Yelling sarcastically out the window as you pass) Thanks for the turn signal Opossum!
When for circumstantial reasons (people nearby, thin apartment walls) you have to have a quiet orgasm, an opossum - otherwise known as "having a silent O."
"Man my parents were sitting on the couch watching a movie and my girlfriend and I were getting it on in the next room - we both had to have an opossum!"
a white person who acts like a black person.
opossums do the same things as raccoons yet are white.
kid 1: look at that guy,he looks like he is trying to be black.
Kid 2: yeah,he is definitely a opossum.
It's an opossum nigger!
Like that thing in Nic's backyard bitch!
