I Don't Understand

This is quite inexplicable.

It's quite common for rugby players to exchange shirts at the end of a match but to exchange shorts as well? That's a first, I think.

There might at least be an explanation if the shorts were different but this picture was taken at the end of the recent World Cup pool match between Japan and Canada and both teams were wearing black shorts.

Granted that the shirts are unique to the player but the shorts are quite generic so why are Luke Thompson and his Canadian counterpart exchanging shorts as well?

I'm gay and I enjoy undressing myself together with another beefy guy undressing himself as much as the next gay boy but this rather defies explanation. Rugby is undeniably a homoerotic sport to begin with but perhaps exchanging shorts is taking things perhaps to the extreme?

On a completely different matter, I wonder what's in there?
