A thingymbob is when you cannot find the correct word for a object/person or place
An example would be :
Steve- “Oh, you know the other night I went to thingymbob down the road.”

Shaniqua- “I don’t have a clue what your talking about!”

Steve- “It’s erm called erm thingymbob and I went with erm thingymbob l. Oh god I’ve forgiot their name already !”

Shaniqua- “Oh you silly thing!”
