Some dude posted a video on TikTok saying he was trying to fart QUIETLY into his grandmother's oxygen tank and she sounds like she's going to croak right there on the spot as she starts gagging on his ass gas.

He compliments her on being a cool granny, then he casually sneaks over to what appears the intake or filter and rips a squeaky toot into it. Then seconds later she's gagging like she's choking on a 2-foot carrot.
