I know I already went and sadly it did not happen to their face so I am not sure if I can include it but as I figure it would be one of the most unpleasant accusations I will go it.
[scene background]
A fellow IT type was cleaning a malware addled laptop courtesy of some people not knowing how to get porn safely
[beer o'clock later that day]
"I would not have cared but every single piece of porn on that machine was boring as all hell"
I have tried to figure out how someone might work it into an insult without foregoing the IT fixing person's discretion but should it be managed in the hypothetical pub environment and it not end* in a massive fight regardless of the insult victim's combat ability it is probably because the sparkly bits happened early from embarrassment.
*"Well yeah I bet your porn is boring" does not work/would be the schoolboy version of it.
