Plenty of time for Clark to consider whether the Vulcan nerve pinch might have any effect on him and whether the socks were really bad enough to warrant it.

He remembers standing in the store and locating the socks by chance and not even thinking twice about how this is definitely the perfect gift for Bruce Wayne, and maybe had he played out the actual giving of it in his mind somewhere between there and standing at the register with these socks and Barry's shirt, he might have come up with something else. Because he wouldn't have anticipated that hand at the back of his neck, and Bruce suddenly close.

And tipping up his chin to meet the kiss when it comes.

Surprised, despite that instinct, heart doing a flip. Clark hovers his hands at his sides before landing them gently on Bruce's arms. Fingers close on folds of fabric, smooth them out again with the warm flat of his palms. Beyond that, he honestly does not do much, maybe enough to inspire a withdraw, but doesn't allow it, closing the space of a millimetre's give with the soft pressure of participatory kiss.

As he'd imagined doing, replaying that one strange encounter a handful of times with the occasional deviation.
