Awkward Fourth Wheel 

n. The state of tagging along on a date in which you are not the only one tagging along. Normally this would not be a problem unless you are already dating someone and have no intention of cheating. This is the rare opportunity where there are TWO awkward third wheels. Take the following example:

Dude, I was totally an awkward fourth wheel on Pete's date with Chelsea because Lauren was sick. Chelsea brought a friend but she was shit ugly plus I have a girlfriend.
