S.O = Significant other

So my bias of B.A.P is the almighty Zelo. And we decided that if my younger sister were to have a brother in the group, it'd be Yougjae. So she pulls out two cups and serves us both lemonade. One was blue and the other was yellow.

My sis: "See, Youngjae and Zelo. Everyone's happy!"

Me: "You get your brother and I get my significant other!"

My sis: *looks at cup* "Your S.O is dirty."

Me: *looks offended* "No he's not! He's and 18 year old boy!...*looks up from iPad* "You may be right..."

Nuff said.
