Idiom: Third Wheel Meaning: - someone who tags along with a group of two other people, usually a romantic couple - an extra person who goes somewhere with a couple (they are an extra person in the group) That's what a third wheel means when you look it up at internet. Is not that I asked to be that person but I ended up always being one. I have always been third wheeling on dates, sometimes I find it awkward but then as time goes by I have gotten used to it. Going to dates, amusement park, name it I think I have been there done that, but the difference is that I'm not one of the person who is feeling the euphoria of love. Sometimes I think will I ever get to feel what they feel on times and moments like that? But now it will just remain as a question.
