It appears to be creeping into rugby union as a lockdown haircut. Those who watched Ireland-England recently will have seen replacement lock Jonny Hill's fine effort, and Steff Evans at Scarlets has been proudly showing his off for a while too.
Hopefully the re-opening of barbers will put an end to it (although I heard a rumour that Evans liked his, and was planning to keep it even after Wales' barbers re-opened last week).
