Kanye West Moment 

When a person interrupts another person saying:
Yo, I'mma let you finish, but.... - then something that was the best to them..

Person 1 (won first place for cake contest): Wow, thanks so much.. I worked hard on my strawberry cake-
Person 2: *gets up and interrupts Person 1* Yo, I'mma let you finish, but chocolate cakes are the best cakes of all time.. all time!!
Person 3: Wow, that dude just had a total Kanye West Moment..

Kanye West Moment 

A moment where someone rudely cuts into a special or beautiful moment and starts shouting about their opinions oblivious to the fact that he's being a jackass.

Your drunk brother had a Kanye West Moment at the wedding...He started shouting in the middle of the ceremony not even thinking about the fact that this is someone ELSE'S MOMENT!
