I am close! My longest bits are at hip already
You might be hip length when...
-You make the mistake of sleeping with long hair and wake up with it stuck under DBF's back :P
-You watch a movie together on the couch and your hair gets stuck under DBF's back
-You freak out because something is tickling you, scarily close to your butcrack and you think it's a creepy bug- and it's your hair. Which in turn leads to a feeling of joy because it's SO CLOSE TO BCL
