couplefest 

An event, party, outing, gathering, activity, that you are invited to and will inevitably end up being you and a bunch of couples.

Dirk: How was the camping trip last night?

Suze: What a couplefest, I was the only single one there and I had to sleep outside under a picnic table.

Couplefew 

an amount of time it will take to do something.

"I will be there in a couplefew"
"How long will this take? A couplefew"

Coupleless 

When you see a couple doing something significant together, like handling their one piece of luggage, and you think, aww they’re not a couple they’re completely united, two souls about to enjoy their love and on their way to their honeymoon.

Ex : Aww, look at them. They’re supremely coupleless. Two souls united in love.
