I thought he said, "He could use a good kiss!" As in it would be good for Leia to kiss him. Of course I have met people in real life who kiss their dog or cat. So it's not that weird.
Huh. Somehow I always thought he said, "He could use a good kiss." Frankly I like it better. In fact I'm going to just insist you're wrong and I'm right cause I find what you insist he said wrong.
What the hell kind of noob has ever even suggested that Chewie is a "pet" and not a sentient intelligent being!!!
As for the scene, Han is having a hard time coping, because it's been a decade or two since any woman has failed to fall for his charm and good looks, and he's never been interested in a woman who either outranks him, or who has better things to do than be his girlfriend. He's always thought of himself as a confident, in-charge kinda guy, but on Hoth... he made the nasty discovery that he has insecurities like everyone else.
I said a person kissing a Wookie is similar to kissing a dog/cat. I didn't mean Chewie had the intelligence of a dog or cat. Just that his whole body is so hairy it's like kissing a dog/cat.
