I did it! I trolled a karen! She was going off on some young girl worker at walmart in the electronics section about masks, so I stood behind her and squirted a fart gas bottle a few times. The employee and I were somewhat protected by the masks we wore, but Karen was very clearly upset, and seemed to just assume I smelled, as she didnt say anything to me, just tried to relocate with the worker. I of course trailed behind, pretending to browse ps4 games, periodically spritzing my foul spray. She eventually made a point if asking if I was ok, as she clearly had had enough of my retchid ass smell, so I quickly unloaded 5 or 6 squirts into her chest and took off out the store.
