Jigglypuffing

Meme. From the Pokemon known as Jigglypuff, who has a habit of scrawling on the faces of those he has put to sleep with his song.
The act of trawling pubs and clubs in the small hours of the morning with a black permanent marker, scrawling randomly on the faces on anyone who is asleep, photographing it, uploading the picture to social media, then moving on to the next venue and repeating.

"The lads and I went out Jigglypuffing last night. It was hilarious!"
