I let out a gigantic, unmistakable, uncontrollable fart at the self-checkout in Marks & Spencers.

It really wasn’t a subtle one, either. It was the kind of sphincter-rippling, slack-anused report where you know that every inch, every ounce of buttock fat was involved in producing that triumphant fanfare, and where the moment after it has occurred, you know that there is absolutely no way you’re going to be able to pass it off as you knocking something over or scraping something along a floor.

There are two practical ways you can really handle a situation like this: either take ownership of the situation and have a good giggle about it with everyone around you, or simply pretend that it didn’t happen, implying that anyone who did happen to hear your eruption was somehow hallucinating. I chose the latter option; I don’t have nearly enough social confidence, particularly around strangers, to pull off some sort of “Good LORD! Did you hear that?!” routine around strangers, though I’m more than happy to parp thunderously in front of close friends and family.

Both responses place anyone near you in something of an awkward position, of course. If you take the former approach, then there’s the unspoken expectation that those nearby will participate in your routine, congratulating you on your impersonation of a baritone brass instrument and generally agreeing that having a good old guff is the peak of humorous funtimes. This, of course, does not take into account those who find bodily functions objectionable, particularly in public, and is likely to make those people feel uncomfortable.

If you take the latter approach, meanwhile, you place the responsibility on the people around you to either comment on the situation or remain quiet. And if you heard the noise that I emitted while swinging my carrier bag full of groceries around from the self-checkout into the trolley, I suspect some people would find it quite difficult not to comment.

Thankfully, the situation resolved itself with probably the optimal outcome. The only person nearby when the incident occurred was someone else who was packing their shopping, and they either chose to remain quiet or simply didn’t notice. There certainly wasn’t any sort of reaction, so if it’s the former I applaud them for their self-control; by the time I was out in the car park I was already in fits of giggles. I hope that when they meet up with their friends later, they enjoy telling the story about the fat man next to them in Marks & Spencer who let rip with a humdinger of a bottom burp without shame while finishing their shopping trip.

I mean it when I say it was uncontrollable, though; it was the sort of guff that doesn’t so much sneak up on you as it is suddenly present, without warning. There was no noticeable brewing time, no bubbling in the gut, no time to prepare — it was simply a case of me apparently moving in the wrong direction and releasing the explosion that had clearly been biding its time in my arse, trapped in a sweaty, fleshy prison, for quite a while.

I am pleased to report, however, that I did not “follow through”, as the vernacular has it. It was simply an extremely loud, explosive trump that was gone almost as soon as it arrived. And now I am home I can have a good laugh about it without worrying about funny looks from strangers. Except for all the strangers I’ve told about it on the Internet with this post.

Oh well. I can’t see your faces.
