Passing Nick Kristof in the Aisle

To lay a fart in someone's face while passing them in an airplane, bus, subway train or other public conveyance where they are denied a means of easy escape and have to take the full blast directly or at least danger close. From an unfortunate incident in late 2019 when two-time Pulitzer Prize winner and New York Times columnist Nicholas Kristof took such a hit while on a U.S. transcontinental flight.

What happened to you?
I tripped on my shoelace while passing Nick Kristof in the aisle to my Calc teacher on the way back from the Mathletes Jamboree and now I've gotta wear this leg boot for 3 weeks.
Yeah, karma can be a bitch.
