Here on Brazil we have this saying too, but I don't know way. Maybe it came with the Japanese immigrants. Dunno.

As far as I understand, staring at the weldingtorches sparks without protection will cause you to wet your bed. No idea about the physiological reason behind this.

vanoss? ( ͡° ͜ʖ ͡°)

poor Orochi...

hail hydra.

No wonder I always wet my bed in my childhood. I think I often play with fire.

I want to be a dish...

That at the end is legit a folklore/saying from my country. If you play with fire, you won't be able to control your bladder lol.

So pu(bg) vr has Dragons now.... Towers.... And its in miramar

We're always recruiting, it's just that I'm lazy to post them (for the time being)

Yeah, in my country they say it too

"Run Away Eight-Headed Demon Dragon!"

Okay, I laughed. :P

Also, if I'm interpreting that idiom correctly, the individuals it is applying to are sitting on their bed holding in their urine while playing with fire, after which they put out the fire with their urine. That sequence of behaviors is disturbing on quite a few levels, and really makes me wonder for the mindset of the people who consider that idiom to be a reasonable one. >.>;

Holy shit, I guess enough people started joining nonames that they stopped asking for assistance.

Dear translators, here in my country, mothers do say that you will wet your bed if you play with fire. What surprised me, is the fact that an Asian culture also had this kind of saying.
