Bloody hell! I’m just totally fed up with your behavior, Fugu. Why do you wet your pants all the time? Oh, don’t tell me again that you are from the ocean. I’ve heard enough of the same excuses.
If 漏れる is "to leak," then this is when you do the leaking yourself. The reason this thing is leaking, though (and it shouldn't be), is because you rushed (らす) the job (because you did it yourself), which is why you know this is to leak something.
The reading comes from 漏れる, so if you know that, you know this! Don't let that memory leak from your head.
