Thunder Thief 

When someone tries stealing your thunder when you are excitedly taking praise for something.

When someone tries to always outshine you.

Example 1:

I climbed mount everest without mount picks or a jacket. What am amazing feat for me!

Thunder Thief would say to everyone "Oh yeh, i did it without shoes, food or oxygen!"

Example 2:

You would say something like this to a group of your friends "I made the best cookies today."

Thunder Thief would say "Whatever they were total garbage. They were crusty and gross."

Reply: You are such a Thunder Thief.
