My mate did that to me when I did motocross we had prepared the bike in the week and he put WD40 on the front and rear brakes . I went down the run off to the start gate and I went straight into the line up waiting to go to the gate . To say I got a round of fucks from the lads at the gate was a understatement . And then I gave my spanner man a round of fucks when I got back to the van . Good stuff WD40 😂
