3rd wheel

Couple's awkward extra

A 3rd wheel is a person who accompanies a couple, creating an awkward dynamic where their presence feels superfluous or intrusive: I felt like a 3rd wheel on their date.

The image suggests something unnecessary—a bicycle only needs two wheels.

Sometimes extended to any unwanted extra person in a social situation.

Also spelled third wheel.
