fifth grade

The last sane year of your life.

I wish I was back in fifth grade where we only had one teacher and walked in lines in the hallway and didn't have homework.

fifth wheel

n. Person who accompanies two (or more) couples in a social situation, who does not have a partner of his or her own. Often the fifth person's attendance is encouraged by one of the well-meaning but ignorant female partners, who may feel sorry for the lonely person, but will inevitably ignore them once the lovemaking starts. It carries the connotation that the fifth person is often an unneccesary and unwelcome addition to the scene in these conditions. Derived from "the fifth wheel of a car", which needing only four wheels to run, has no need of a fifth.

"Jim and Sue, Mike and Sally invited me to come camping with them, but I refused as I would only have been the fifth wheel on my own!"

Fifth Wheel

The person in a friend group that’s technically part of said friend group but is only actually part of it when one is missing. Like a fifth spare tire.

“I wish I had some better friends, mine only treat me like a fifth wheel.”

Fake, phony, less than 100% genuine.

I thought she and I were really good friends, but after hearing what she said about me, I realized she was being fifty.
