-The act of stealing the spotlight and making every story about yourself.
-Stealing the spotlight
Example 2: Your friend walks in (Friend A) obviously having a bad day and begins talking with your other room mate (Friend B) about it all. Friend A says something to the affect of "My dog just just died and I failed my chemistry exam" and you but in and say, "Oh my gosh I had to take an exam today and I didn't even know half the questions on it and then the rest of my entire day was completely ruined. I think I might get a bad grade for my class this semester. Isn't that terrible? I mean it really upsets me." and so on and so forth.
-The proper usage here would be for friend B to say to you, "Slow down buddy your getting Tyra Banks Syndrome" or "Wow thanks for that Tyra"
This is the person who makes every story about themselves. Extremely rude and annoying
