Thinking about the looks wade must get when he calls this big, buff lumberjack of a man who looks like he spends hours a day working out babygirl and peanut and princess. People think he's gonna get punched in the face. Wade calls him cupcake and everyone at the bar thinks he's gonna get his ass beat but Logan just grumbles a bit like an old cat.
Logan likes the names, secretly. Especially peanut. It's just for him. Proof that he's important to wade. Wade doesn't call anyone else the other names he's given Logan, of course, and he treasures those too even if he grumps about them but peanut is his little bit of proof that Wade values him. He was hated it his world and now he's Wade's favouritest person ever. He soaks it up, letting Wade say and do whatever he wants because that's his person. Especially when it's only them. If they're alone he lets wade be as cuddly as he likes because even though he can't ask for it he wants to be just as much of a clingy bastard. He doesn't even put up a token protest unless they're around someone else it's really cute.
