Preferring to stay secretive, Wolf smiled at Mao as he asked him about their hypothetical sex life in the alternate dimension where Mao wanted that from him. Maybe it was mean, but Wolf was more amused making Mao wonder than revealing which way it would be.
And, no, Wolf didn't really think he was that much wiser than Mao or Luke because he was in college. Things were different at Hobbs because people tended to be older there and a lot of classes were mixed with teens and adults alike, but judgmental assholes still existed. Luke was going to have to get over his personal hurdles or it'd never work, and hopefully a little thing like graduating high school would help. Wolf knew that, he just liked insulting them.
"No clue," Wolf said laughingly, only knowing what 'GAAAAY' in lip-reading was because they'd discussed such things before. "I think it just means we're way cooler than him." Wolf would have gone on, but past Mao he saw his mother coming into the room and she effectively captured his attention.
"Tell him he has to work for dinner like I do," Wolf retorted with a grin, going back to signing energetically as he spoke.
It didn't take Wolf long to pick himself up and head over to Lulu for a hug, though he didn't prolong the gesture because he needed to see her response to his next question. "Where's mom? Still at work?"
