It is the world's dumbest animal.
I have recently started calling dumb guys 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!"
