He said either first base or second base while dangling off her, and told her he'd tell Wolverine he'd gotten to second or third. Sorry, I don't have the comic to hand.
In his defence, he was dangling off her in a legitimate combat kind of way, not really skeevy, and she spent a lot of the issue trying to arrest him for not being registered, so I can see him wanting to annoy her. Still, the sexualized jokes didn't really seem in character for Peter.
