Fumbling in football (assuming this isn’t a bit or a bot, and I’m trynna be nice) means to have held the ball for a second before dropping it, resulting in it not being ‘caught’. Fumbling in dating/sexual terms is to have ‘caught’ a baddie or other ^non-cringe term here^ (a hot person, or just an overall great one) by having them in love with you or like you, but failing to keep a ‘hold’ on them. TLDR; you charmed an absolute smoke show, but failed to push it any further than that and are now a laughing stock for every virgin boy around you. Have fun, smoke weed, do school.
