I'm fairly sure it was just in keeping with the whole leather/biker look the that the video (and Freddie) was going for.
It is, however, a very cool Tshirt. You can get it here, by the way. link. I bought it a couple of months back.
....Just need the Jacket now!
Thanks for your replies!
This gave some new thoughts, because I've always thought it was bad language of some kind. I asked my English teacher when I was 10 years old, but he didn't want to explain it to me because it was meaning something bad.
So, thank you!

Apparently Freddie really wanted John to wear a T-shirt that said 'Toast Rack'.
'Bike It' was a compromise.
