stealth woobie
a person who is a woobie is typically a big guy, good at comforting, very protective, great huggers, think Hoss Cartwright, but a "stealth woobie" is a guy of average build and height but he emanates protectiveness.
Daniel was her stealth woobie. He wasn't as big and buff as some of the other guys but there wasn't anyone who could simply hold her and make her feel safe and secure quite like he could.
