third wheel
Unwanted romantic extra
Third wheel describes a person who accompanies a couple, creating an awkward imbalance—someone present but not fully part of the dynamic: I felt like a third wheel on their date.
The image comes from vehicles: two wheels make a bicycle, but a third is superfluous.
The phrase implies being unwanted or out of place, though sometimes used self-deprecatingly.
