That one one person that if you're too close too, or spoil too much, some people out there start thinking you're into incest.
Boy #1: My sis said she's been wanting some chocolate recently, guess I'll surprise her.
Boy #2: Your sister?
Boy #1: Yeah, why...?
Boy #2: You too are always so close, is there some incest thing going on with you two?
Boy #1: You watch too much porn and anime bro...

Get the Sistermug. The actor/singer/celebrity that could be the little brother or sister of anyone with a little brother or sister, since this person actually was somebody's little brother or sister growing up.
If the singer/actor thought his/her boy/girl next door image was bad, he/she could have always got stuck with the America's little brother/sister image of the other actor/singer/pop star.

Get the Blario sistersmug. If everyone was a thought brother/sister, there wouldn't be anyone more in charge than the next, there would be no hierarchy.
A thought brother/sister must be a dream to wake up from, since people seem to want a thought leader more than they want one of those.
