The napalm rolled over and down the front of the recessed embrasure.

My friend explains that troublemaking party animals see how many people can stand on the deck of an unfortunate boat and eventually they submerge it -- the canal equivalent of rolling over a car.

我朋友解释说，那些参加派对捣蛋鬼想看甲板上能站多少人，结果把船搞沉了，相当于里翻车吧。
