Most of us can relate to this prank that we may have been unfortunate enough to be on the wrong side of.
You could be scrolling through social media, see a video that you may be interested in ... only for the video to be an audio overlay of sex noises.
Can be annoying but also can be extremely funny.
Well, three lads in the UK have taken this prank to a whole other level, trolling a BBC journalist with sex noises during a live cross on breakfast television.
The journalist, to her credit, soldiers through the cross, although watch the video right through to the end to see her hilarious reaction.
