By definition this a lame, but worse. This generally happens when a younger sister thinks she is not lame, but truly is lame.

An absolutely beautiful, kind, big hearted, caring, loving, generous, sweet, cute catooo who makes the best girlfriend even to walk the surface of the planet. She can make anyone's day 200X better by just talking to them. Also a massive NF fangirl. Overall an amazing, wonderful, fantastic person.
