Indoor Furniture is slang for a girls box in guy lingo. Ask a brother how the girl's indoor furniture feels and you are effectively asking "how'd the inside of her vagina feel?"

Other common uses:
"Did you get to see the indoor furniture?"

"Was the indoor furniture comfortable?"
"I spilled all over her indoor furniture!"

A pick me is a woman that is willing to do anything for male approval. She will embarrass or throw other women under the bus to achieve this goal. The unfortunate thing about a pick me is usually the men they are trying to seek approval from are of poor quality and treat women badly, leaving little real benefit for the pick me.
