How to?

Step 1: Ask for bombi

Step 2: go to the border of the t-spawn area at the truck

step 3: run facing the nose of the truck and throw bomb while jumping

You did it! now the only way your mates can get the bomb is if they boost on the truck. In my one year of bomb throwing experience that rarely happenned. probably because my rank is silver 1/2. If your mates refuse to give you the bomb because they saw your do the funny move just kill them and take the bomb against their will.

If your teammates block the truck ask a friend to runboost you on top of the truck. If you do not have a friend in your team you might have to kill them.
