Get a Third Wheel mug for your papa James.
One who deters the socialization of a couple, perhaps when being invited out of pitty or through a feeling of duty. This person may be eased into the situation by being allowed to stay in an envirnment he or she has become accustomed to (perhaps a kitchen, where the third wheel can bake cookies for the couple.) The third wheel may feel uncomfortable about watching the couple canoodle on his her her sofa, but none of this is taken into consideration.

Get a Third Wheel mug for your boyfriend Manley.
Where one person hangs out with two people who are dating in situations and places where couples usually hang out like at the movies or at restaurants.

Third wheelers make the situation extremely awkward for a couple to show affection towards each other or talk about things pertaining to their relationship.

Third wheelers also invade time with potential couples. Usually they are invited to hang out because of pity and consideration. It is also awkward for the one who unintentionally becomes the third wheel when the couple sort of distances themselves from them so that they can do things as a couple.
I'm not going to the movies with you guys tonight, I don't want to be a third wheel. It is like watching a poorly scripted romance movie!
