Hello all. I am not from Wales, nor have I ever been to Wales or anywhere in the UK, but recently I discovered the [“Oi Mush” Song](https://www.youtube.com/watch?v=lbBPRmNB2g8) from the 1990s which, from what I’ve read online, is fairly well-known in Wales and was created by a man named Paul Allen from Swansea. After having found that, I then discovered Paul Allen’s [“The Welsh Christmas Song”](https://www.youtube.com/watch?v=Pj3m1hkWCIY). In both of these songs, the singer says things like “I’ll do your f\*\*\*ing car!” and “They’ve done your f\*\*\*ing sleigh!”. What exactly does he mean by this? I’d suppose it’s either stealing the vehicle or vandalising it, but I’m not sure. I could not find any definitive answers online.
