What it means
Being on the pull means you're out with romance on the agenda, usually in the low-stakes, night-out sense. You're dressed for it, chat switched on, scanning the room, hoping to flirt, pull, or at least not waste a good haircut. It's very UK and usually tied to pubs, clubs, and big confidence with patchy results.
